Velvet Premium Comfort 8 Youth Diapers Review

*For more information on how I do reviews see Diaper Test Methodology. For a list of all product reviews see the Product Index.


 
  

Summary

When procuring the Darlings 8 youth diaper I also discovered a more budget-friendly variant of it sold as the Velvet Premium Comfort. Along with the Darlings 8, the size 8 of the Velvet diaper sits at the top of the market as the largest youth diaper sold in retail stores (again only in Kuwait). Both have a recommended weight-based sizing of 35 kg+ (77 lbs+). These fill a rather underserved gap between baby and adult diapers. Most other products that fill this gap, like Goodnites, tend to be a protective underwear style.

The structure and materials of the Velvet 8 are very similar to the Darlings 8. Both are tab-style diapers with a single hook & loop tab per side coupled with a rectangular fastener landing zone at the front. The biggest difference between the two is the backsheet pattern and the fastener mechanism. These have a particularly interesting fastener mechanism that I haven’t seen elsewhere, with a narrow region of elastic material connecting the tapes to the rear wings. The rear wings themselves are made of an inelastic material. It looks flimsier than the Darlings 8 fastener mechanism, but in practice I found it quite effective and slightly more durable. Otherwise, the performance between the two was pretty similar and the Velvet 8 generally outperformed the Darlings 8 in terms of absorbency.

As a reviewer who is primarily focused on adult incontinence products I find it interesting to see the innovations done in youth products that haven’t necessarily made it into adult equivalents. The small sizing makes these reviews particularly challenging and the number of products in this category that are even remotely feasible to review are quite limited.

Surface Dampness Rating: 8

The Velvet 8 was similar to the Darlings 8 when it came to resistance against surface dampness. Both diapers proved remarkably strong given their level of absorbency. During the paper towel check in the lab test there was no significant surface dampness after the first wetting. There was more from the second wetting, but not quite the same extent. Both diapers were a bit susceptible to initial pooling on the second wetting, but it was a little less noticeable on this diaper during the lab test. In real world testing I also rarely noticed any surface dampness and noticed these diapers to be exceptionally resistant to pressout moisture.

Padding to Absorbency Score: 1.32 ml / cm2 (0.30 oz / in2)

Standing-Sitting Rating: 3

The Velvet 8 demonstrated a strong performance given its sizing when tested when standing and sitting. Like the similar Darlings 8 diaper, I was clearly above the intended sizing for this diaper, but again gave it a test to assess its relative performance. The first wetting while standing was fully absorbed without any signs of leakage, though there was some initial pooling in the mid-section that subsided a short while later. Once absorbed the padding swelled a bit, but moisture felt well contained without notable surface dampness. There wasn’t any obvious pressout moisture upon sitting shortly afterward and I found it more comparable to the Pampers or EasyUps than the Goodnites or Pull-Ups in this regard. Also, unlike the similar Darlings 8, there wasn’t any leakage even after an extended time seated. At this point the front padding was mostly wet but there was still a bit of dry padding at the rear. The second wetting while seated was clearly going to leak and quickly pooled in the front before settling back into the mid padding where a large leak formed through the leg gathers. The leak guards were surprisingly strong, though it may have been partly due to the tight fit. At the end of the test there was even a bit of remaining dry padding at the rear where moisture couldn’t quite wick to before the leak. Overall absorbency was decent and I’d expect for its targeted sizing it could quite consistently manage 1 or 2 wettings without leakage.

Total Absorbed Volume: 680 ml (24 oz)
Total Wettings: 2
Used to Total Padding Ratio: 100%
Padding to Absorbency Score: 1.48 ml / cm2 (0.34 oz / in2)

Lying Down Rating: 3

The Velvet 8 performed surprisingly well when tested while lying down. I was certain it would leak on the first wetting and it did indeed come close, but somehow the barriers managed to contain it. Moisture pushed both directions backward into the rear padding and forward into the front padding. There was notable pooling in the front padding and it felt like it might push through the leak guards and out the side, but it remained contained long enough for the padding to capture the excess and there was no obvious leakage. As you might expect with me being above this diaper’s targeted sizing, the padding was nearly all wet at this point with very little obvious remaining dry padding. That said, moisture was well contained and I only really noticed a bit of swelling without any obvious pressout moisture and little noticeable surface dampness. The second wetting was very clearly going to leak. Initially there was substantial pooling up the front with significant leaks through the front leak guards into the wings as well as leaks through the leg gathers. The diaper was clearly saturated at this point, with pressout and surface dampness quite obvious. The overall absorbency was impressive for a youth diaper and comparable to what I’ve seen from some retail adult diapers. It performed better than the slightly more expensive Darlings diaper and better than any other youth diapers or protective underwear tested so far aside from the Goodnites XXL. For its intended sizing this diaper should be a good choice for managing bedwetting.

Daily Wear and Bedwetting

Like most of the youth products reviewed so far, I was far too large to test these from a practical daily living standpoint. I could fasten the diaper around my waist but the fastener placement wasn’t ideal and, when under continuous stretch or strain from different movements, the glue holding the fastener extensions to the rear wings would eventually give out causing it to pop off. It generally held out for a longer duration than the Darlings 8, which was a bit more susceptible to this problem. The stretchy tab extenders were pretty interesting and oddly enough caused a different fit, with the rear of this diaper sitting much higher than the front compared with the Darlings 8. To extend the life of these I would occasionally have to re-glue the fastener extension to the rear wings and I found that easier to do with these than the Darlings diapers. I also found these to be slightly larger than the Darlings 8 with a total diaper area of 1670 cm2 (258 in2) vs 1635 cm2 (253 in2) and padding area of 450 cm2 (69.8 in2) vs 460 cm2 (71.3 in2). The sizing is about equivalent to the previous Goodnites L/XL or perhaps the current L. These diapers generally performed better in terms of absorbency. They consistently absorbed a full wetting without leaks and were remarkably resistant to pressout. The rate of absorption may have been slightly better, though both these and the Darlings will initially have noticeable pooling after a wetting. Unlike the Pampers products, these don’t have any obvious moisture channels, so perhaps with better channeling they could absorb even faster with less pooling. In terms of market fit, I feel they again likely fill the gap of a product like Goodnites and perhaps act as a bridge product for special needs youths. These are a more budget friendly product than the Darlings diapers and have a relatively low unit price in their home market for what you get with them. That said, the quality and particularly resistance to pressout/surface dampness remains impressive and it’s certainly a product I’d consider if more widely available and of a size I could properly fit.


Suitability for Bowel Incontinence: 8

The Velvet 8 diaper should perform as well as any youth diaper for bowel containment. I’m ranking it the same as the Darlings 8 diaper in this regard. Like most youth diapers, the padding doesn’t rise all the way up the rear, but the backsheet coverage is far greater up the rear and this diaper seems to have a fastener design that pulls the rear much higher compared with the front. It also has a cloth-like backsheet and, as is the case for many similar diapers, the breathability may reduce its ability to contain odors. For its target sizing I imagine this should be a decent diaper for bowel containment, but not quite at the top.

 

Wear & Tear Tests


Fitting

The Velvet 8 is a youth-style tabbed diaper with a single hook & loop fastener per side and a narrow area of stretchy material extending behind the fastener. It features a rectangular landing zone and like other youth diapers has small tabs from the front of the diaper that form the front wings. This diaper is very similar to the Darlings 8 in dimensions, perhaps even slightly larger as I measured a little more in diaper and padding length. Both diapers are designed for youths larger than 35 kg (77 lbs) and no other standard retailing youth-style diaper comes close to this in terms of marketed sizing. Once again, the sizing of these is similar to the old Goodnites L/XL or perhaps the current generation of Goodnites L. The padding area is the same as the Pampers UK 8 at 460 cm2 / 71.3 in2, but the surface area of the diaper is much larger at 1670 cm2 / 259 in2 vs 1381 cm2 / 214 in2 for the Pampers product. That gives it a slightly larger fit than the Goodnites XL in terms of surface area, although that’s partly due to the difference in design where the sides of the Goodnites are stretchier and cover more when actually worn. I found it notable that the structure of this diaper gives it a higher rise up the rear compared with the Darlings diaper. Unlike the Darlings diaper, the rear wings on this diaper don’t have any stretch on their own, but there’s a narrow area of elastic material that gives them flexibility for fastening. Unstretched, the tabs will fasten on the landing zone for a hips/waist of about 62 cm (24.4”), the same as the Darlings diaper. The stretchy material connecting the fasteners has about 2 cm (0.79”) of additional stretch per side, so realistically at full stretch these will fit the landing zone on a maximum hips/waist of 66 cm (26”), which is a little short of the Darlings max stretch fit. However, the maximum feasible fit to connect it around a waist regardless of fastener is about the same for both around 96.5 cm (38”), which is achieved by connecting the fasteners directly to the front wing tabs. These tabs are strongly held in place and won’t come undone, but under a long enough period of stretch the part holding the stretchy material to the rear wings will eventually pull loose. So even though these are dimensionally slightly larger than the Darlings 8, the realistic range of fit is a bit narrower with a best fit between 62 cm (24.4”) and  66 cm (26”).

3.1 Velvet Premium Comfort 8 Fastener

Ease-of-Use Rating: 8

The Velvet 8 diaper should generally be quite user friendly. Though I rank it slightly lower than the Darlings 8 due to the more limited range of fit. The fasteners are a hook & loop material and they will easily attach and detach from the landing zone without damaging material or losing their adhesiveness. Like the Darlings diaper they have a strong grip and will hold in place with little-to-no movement once attached. From my testing they had the same fastener malfunction as the Darlings, where those who wear these with a persistent stretch will find the stretchy fastener bit can pull out of place. Although, I actually found that part to be a little more durable on these (possibly just the batches tested). Moreover, these diapers don’t include a wetness indicator, which can be helpful in some caregiver environments. On the plus side, like the Darlings diapers, these also come in a very wide range of sizing, so youths could wear these for many years and they will likely act as a transitional product for those experiencing bedwetting.

3.2 Velvet Premium Comfort 8 Diaper Fit

 

Comfort


Comfort Rating (dry): 9

The Velvet 8 is about the same as the Darlings 8 when it comes to dry comfort. It’s slightly larger, but otherwise the biggest obvious difference is the fastener system and for anyone able to fit this with the fasteners on the landing zone you wouldn’t really notice because the stretchy fastener extension on these would be sitting completely over the backsheet. The general topsheet and backsheet material is about the same and in both cases very soft and comfortable. These diapers are highly breathable and barely noticeable in their dry state. The fasteners also have an incredibly strong grip that won’t give out over time (minus the overstretch issue I’ve mentioned earlier, which wouldn’t generally be the case for someone more appropriately sized for these). The padding and structure are otherwise highly durable and I didn’t notice any significant clumping or tearing. The rear waistband gives this diaper a decent stretch so it isn’t purely superficial like some, but it’s not quite as stretchy as the Darlings diaper because of the smaller area of elastic material on the rear wings.


Comfort Rating (wet): 9

I rank the Velvet 8 diaper about the same as the Darlings 8 diaper when it comes to wet comfort. The primary difference between the two diapers is the front wings, but both fastener designs are more than strong enough to prevent any sagging. In the lab test I noticed less pooling with this diaper, though in real world testing they weren’t too dissimilar. It’s possible that the slightly faster wicking on this diaper was the reason tested absorbencies generally ended up greater than the very similar Darlings 8. Again, if you’re a size that can properly fit these I’m certain you’d find them equally comfortable when wet compared with their dry state.

3.3 Velvet Premium Comfort 8 Topsheet and Backsheet

Durability

Dry Padding Deterioration Proportion: 5% (topsheet), 5.3% (backsheet)
Shake Deterioration Test: 4 shakes to deterioration


Durability Rating (dry): 9

Once again, I pushed this diaper to its limit by testing at a size larger than its intended market. I found it to be a little more durable than the Darlings 8 diaper, primarily because the bit holding the fastener extension to the rear wing held on a bit strong. It still wasn’t foolproof and I had several of them rip off, but it was notably better. Sitting for an extended period of time essentially guaranteed a failure in the Darlings diaper, whereas in this diaper the fasteners connector bit would only really start to weaken after various different exercises or movements put pressure on the fasteners and eventually they gave out. The fastener grip itself was outstanding and they will easily hold up to anything you could throw at them without slipping or coming loose once fastened. In terms of padding condition, I never noticed any significant clumping or tearing and considering I pushed them to their limit the padding was in impressive shape at the end of the dry durability test. Like the Darlings diaper, I feel this diaper could be improved with a better adhesive to keep the fastener extensions connected to the rear wings, but otherwise I can’t find any durability faults in this diaper.


Durability Rating (wet): 9

The Velvet 8 diaper performed strongly when tested for wet durability and I again rank it a little higher than the Darlings diaper because the fastener extension weakness was less pronounced in this diaper. Otherwise, it performed similarly with the padding showing no obvious additional susceptibility to clumping or tearing when wet. The fasteners have a remarkably strong grip for their size once attached and don’t shift or loosen with wear. Structurally this is a highly durable diaper that’s made of good quality, strong materials. The bit connecting the fastener extension to the wings could be a bit stronger, but otherwise they’re about as durable as you could ask for in a diaper.

3.4 Velvet Premium Comfort 8 Dry Test Deterioration


Discretion Tests


Profile

Front Rise Above Waistline (Jeans, Sweatpants): 0 cm (0"), 1 cm (0.4")
Back Rise Above Waistline (Jeans, Sweatpants): 0 cm (0"), 0 cm (0")
Side Rise Above Waistline (Jeans, Sweatpants): 0 cm (0"), 0 cm (0")

Profile Discretion Rating: 10

The Velvet 8 diaper is about the same as the Darlings diaper when it comes to profile discretion, which itself is similar to the Goodnites L/XL. You couldn’t really ask for a more discreet diaper than this, especially given its absorbency level. I didn’t notice any hint of a diaper bulge and the backsheet pattern is pretty subtle and wouldn’t be super noticeable above the waistline.

4.2 Velvet Premium Comfort 8 Sweats Profile (left) vs Normal Underwear (right) 


Noise

Noise Rating: 10

The Velvet 8 diaper didn’t produce any obvious sound when tested for noise discretion. These diapers have a cloth-like backsheet that doesn’t generate much resistance with movement. If you’re able to fit them I wouldn’t expect anyone to notice.


4.3 Velvet Premium Comfort 8 Noise Profile

Odor Reduction

Odor Reduction Rating: 8

The padding and structure of the Velvet 8 diaper is nearly the same as the Darlings 8 diaper aside from the different fastener mechanism and slight dimensional differences. The padding has a very strong resistance to surface dampness and ultimately odor formation. Being cloth-backed they can be a bit susceptible to odors if they do form and the padding doesn’t run very far up the rear of the diaper. But considering the sizing these should be more than sufficient for resisting odors.

NorthShore MegaMax Airlock Adult Diaper Review

*For more information on how I do reviews see Diaper Test Methodology. For a list of all product reviews see the Product Index.


 
  

Summary

The NorthShore MegaMax Airlock is a high absorbency cloth-backed diaper that closely resembles the popular plastic-backed NorthShore MegaMax Overnight in structure and performance. While the plastic backed MegaMax is rated at 12 hours protection, these are rated slightly less at 9 hours. Both diapers have a distinct honeycomb padding that's highly resistant to clumping or pressout. Unlike the plastic-backed MegaMax, the white version of the Airlock additionally has a wetness indicator. However, sizing and backsheet color are a bit more limited in this diaper compared with the plastic-backed version. This diaper has what I consider to be a “hybrid” design, with a cloth-like backsheet material but landing zone and tape fasteners you’d more typically find on a plastic backed diaper (cloth-like diapers typically use a hook & loop fastener). It looks like the previous version of this diaper, the “NorthShore MegaMax Air” did indeed use hook & loop fasteners but they’ve transitioned away from that. Since I started reviewing, the NorthShore product lineup has greatly expanded. In addition to the MegaMax line, they also have the NorthShore Supreme and AirSupreme as well as a new lite version of the plastic-backed MegaMax and boosters/inserts among other things.

I’ve received a lot of positive feedback on the plastic-baked MegaMax over the years and was pretty impressed with my previous review of it, so I was quite interested to see how this diaper would compare. Overall, I was quite happy with the performance of this diaper. Though being near the sizing cutoff I may have struggled to get as accurate a read on overall absorbency as I typically would. In any case, I’d expect it to absorb up to 3 wettings without leaks for most properly fitted wearers, perhaps more if worn primarily while standing. It would be a good choice for bedwetters. In daily wear it could be a bit bulky and you’d want to be mindful of what you wear over it to preserve discretion. I’d like to give a special thanks to the donation that contributed to this review! I’m truly grateful for all the donations and support I’ve received over the years since I started this project!

Additionally, I’m happy to announce I’ve become an official partner with NorthShore Care Supply! I’ve been very impressed with their products and, as I’ve mentioned previously, I have a great appreciation for the level of engagement the company has on product development.

Surface Dampness Rating: 9

The honeycomb padding of the NorthShore Airlock is virtually identical to the NorthShore MegaMax aside from being slightly less absorbent and therefore it comes as no surprise that performance is nearly identical as well. During the lab test it demonstrated barely a hint of surface dampness until the 3rd wetting and even then it was far from saturated. This is backed up by real world testing, where I never noticed much in the way of surface dampness during my testing. Like the MegaMax, the only downside is that absorption can be a little slow and that leads to temporary pooling immediately after a wetting.

Standing-Sitting Rating: 7

The NorthShore Airlock was a reasonably good performer when tested while standing and sitting though it leaked a bit earlier than I’d expected. The first wetting while standing was comfortably absorbed with little in the way of pooling and no sign of leaks. Absorption was quick with moisture sinking/spreading into the middle padding and the wetting was hardly noticeable in terms of dampness. There was no hint of any leakage upon sitting shortly afterward. The second wetting while seated initially didn’t leak but pooling developed in the front of the diaper and leaked through some weakness in the front leg gather. I suspect this may have partly been due to a looser fit for me than I’d typically wear (I was right at the bottom of the suggested fit range for the medium size). This sizing cutoff was one of the reasons I went with a small size for my initial review of the NorthShore MegaMax. The pooling combined with the expanded padding below from the previous wetting created a dam effect, so any gaps in the leak barriers were bound to produce a leak in this position. There was still a large amount of dry padding at the front and rear of the diaper at the end of the test, so it clearly could have absorbed a lot more. I feel generally this diaper will work well for daily wear and will probably absorb up to 3 wettings while standing or seated, but you’ll want to test the sizing to make sure you get a snug enough fit.

Total Absorbed Volume: 1392 ml (49.1 oz)
Total Wettings: 3
Used to Total Padding Ratio: 66%
Padding to Absorbency Score: 0.78 ml / cm2 (0.18 oz / in2)

Lying Down Rating: 8

The NorthShore Airlock performed quite well when tested while lying down. The first wetting was easily absorbed with very little pooling and moisture quickly settled in the middle padding. Afterward it was barely noticeable aside from a little more padding thickness and the diaper continued to feel quite dry. The diaper continued to perform well on the second wetting with only a brief period of pooling and no signs of leaks. This time moisture made it further back into the rear padding, but it still felt quite dry afterward and there was considerable dry padding up the front and rear of the diaper. On the third wetting there was a more extended period of pooling in the diapers mid-section though more moisture did reach the dry rear padding as well. During this time there was a small leak through the left rear leg gather, so I ended the test at that. The diaper clearly had far more capacity and it seems the combination of pooling and a slight gap around that barrier was enough to cause the leak. At the end of the test there was still a significant amount of dry padding up the front and rear and it didn’t feel particularly saturated or uncomfortable at the time of the leak. In general I’d expect this diaper to manage up to 3 wettings before leakage would be a concern and it should be generally quite sufficient for managing bedwetting.

Daily Wear and Bedwetting

I had pretty good performance with the NorthShore Airlock when tested for daytime wear and bedwetting. The diaper has an impressive absorbency so the padding never really got near the point of saturation before I felt like I needed a change. The biggest challenge for me was sizing. I feel the sizing was a little on the large size for me so gaps could form more easily between the leak guards and my thighs. This was mainly an issue during or shortly after a wetting, because, once absorbed, moisture was very well contained and not susceptible to pressout. However, I believe the same topsheet materials/barrier that makes it so resistant to pressout also may have resulted in a slower absorption time, so you can get moisture pooling for a short while before it’s eventually wicked through the padding. During that point, if any of it nears the barriers you risk a leak well before the diaper has reached capacity. I’d say this is mostly a risk when sitting or side-sleeping, particularly if you don’t have a perfectly snug fit. This problem is more common on the second or third wetting because the padding swelling will create a dam effect, causing more to pool up in one area. I typically wear a medium sized diaper but my waist size is right near the cutoff for that size on this one, so it likely fit a little too large and amplified the gaps. Otherwise, the backsheet is moisture impermeable and never showed a hint of perspiration when wet. In terms of comfort the materials are pretty soft and not prone to chafing. I wouldn’t say it’s the softest on the market, but I didn’t find softness/comfort to be an issue. I don’t feel there’s a huge difference between this diaper and the plastic-backed NorthShore MegaMax. The construction is similar and, while this one may have been slightly better for heat dissipation, the backsheet material is a similar thickness and the inner materials are pretty much identical. The absorbency is slightly less, which lines up with NorthShore’s assessment of the diaper. Even so, I feel this absorbency would be quite sufficient for most people's needs and if you’re happy with that diaper I feel this one is a pretty low risk to try. I was quite impressed with its durability as I never had any issues with tapes coming undone, sagging, or padding deterioration during daily activities. However, it is quite bulky and perhaps better for wear around the home or bedwetting than going out in. That said, I took this diaper on previous travels and found that with adequate outerwear it can be concealed and doesn’t produce a degree of noise anyone would likely notice. If you like the NorthShore MegaMax but want something slightly more discreet this would be an excellent choice.


Suitability for Bowel Incontinence: 8

I rank the NorthShore Airlock at the same level as the NorthShore MegaMax when it comes to suitability for bowel incontinence. They both would make an excellent choice and both have generous padding and a snug fit. The main challenges are the same with potential leak guard weakness/gaps and slower absorption (if dealing with liquid fecal loss). On the plus side, anything absorbed is very well locked in and they have pretty good resistance to surface dampness. I think most will find them suitable for their needs, but I can’t quite rank them among the best performers.

 

Wear & Tear Tests


Fitting

The NorthShore Airlock has what I’d consider a “hybrid” design with a cloth-like backsheet, plastic landing zone and tape adhesive fasteners (cloth-like diapers typically have hook & loop fasteners). The landing zone and fasteners are nearly identical to plastic-backed NorthShore MegaMax but slightly narrower. The honeycomb padding configuration and layout are also similar to the plastic-backed NorthShore MegaMax, but it’s only about 80% of the weight. These also have a larger North American sizing for fit, so if you fall at the bottom of a particular European sizing you may find these a bit large and want to go down a size. The fasteners are good quality and have an incredibly strong grip. They can be refastened multiple times without losing their adhesiveness and can be repositioned anywhere on the landing zone.

3.1 NorthShore MegaMax Airlock Fastener

Ease-of-Use Rating: 9

I rank the NorthShore Airlock similar to the MegaMax in terms of ease-of-use. Both are highly user-friendly and share a similar design. I found it easy to consistently achieve and maintain a snug fit with this diaper. The front and rear waistbands are large and help keep it snug at the waistline. The landing zone covers a large area so fasteners can be adjusted to a variety of body shapes. Fastener placement outside the landing zone is not advisable because it will damage the backsheet. It’s pretty easy to attach, detach and reattach the tapes, which would be particularly convenient for those who can reach the toilet at times or aren’t dual-incontinent. The biggest potential challenge in these diapers is that fasteners are almost too grippy and can be difficult to remove when fastened, which could be a challenge for those with a weaker grip. I’ve also found that on rare occasions removing them can pull bits of the landing zone up with the fastener, which may compromise leak protection. However, I give these a slight edge over the plastic-backed MegaMax in that they have a wetness indicator, making them a little easier to use for caregivers.

3.2 NorthShore MegaMax Airlock Diaper Fit

Comfort


Comfort Rating (dry): 9

I found the NorthShore Airlock to be very similar to the NorthShore MegaMax with respect to comfort. The internal material construction is pretty much identical to that diaper and the primary difference is the outer backsheet material. In terms of cloth-backed diapers the backsheet material on these is of a firmer, more papery variety. It’s breathable, but not so much that I feel it has a distinct edge over the plastic MegaMax when it comes to heat dissipation (both backsheet types are similar thickness and prioritize avoiding leaks over airflow). This includes the backsheet on the wings, which is where cloth-backed diapers typically have the greatest breathability. That said, this diaper, like the MegaMax, is quite good at heat dissipation. The padding is highly resistant to clumping or tearing so you’re unlikely to notice any discomfort due to that. It doesn’t have the softest material construction, but certainly enough to rank it in the top contenders for dry comfort.


Comfort Rating (wet): 10

The NorthShore Airlock is a very comfortable diaper in its wet state. I didn’t find the feel to be noticeably different from its dry state other than a bit more padding thickness. Like the NorthShore MegaMax, the topsheet on this diaper repels moisture from coming back up to the wearer’s skin giving it exceptional resistance to surface dampness. Moreover, moisture in the padding doesn’t produce clumping or tearing, which can lead to discomfort. The tapes also have a very strong fit, so you won’t need to worry about sagging from this diaper. I can’t really think of any flaws in this diaper when it comes to wet comfort, and thus it gets top marks.

3.3 NorthShore MegaMax Airlock Topsheet and Backsheet

Durability

Dry Padding Deterioration Proportion: 4.4% (topsheet), 8.1% (backsheet)
Shake Deterioration Test: 3 shakes to deterioration


Durability Rating (dry): 9

I found the NorthShore Airlock to be highly durable when tested for dry durability. I found it had less padding collapse compared with the earlier tested MegaMax. It could be down to the difference in testing batches between the years, sizing or backsheet differences, but it was different enough that I considered it in my scoring. The front wing padding on this diaper still is a little susceptible to breakdown, but it’s not critical to function and the core padding was in great shape after extended testing. The tapes have an incredibly strong grip; so much so, that you could tear off bits of the landing zone if you’re not careful. But you never need to worry about this diaper sagging or coming loose on you and the tapes can consistently be refastened without issue. They are a bit bulky, but if you can make them work these would be a great choice for active wear.


Durability Rating (wet): 9

I found no difference in NorthShore Airlock durability between its wet and dry state. It excelled in both circumstances. In its wet state the core honeycomb padding remained fully intact without any hint of clumping or tearing. I had no issue with the fasteners shifting or coming undone. They held strong during testing and easily carried the weight of a fully wet diaper. It wasn’t quite at the level of the NorthShore Supreme or Drylife SlipSuper in this regard, but very close. I rank it the same in its wet state as in the dry state.

Discretion Tests


Profile

Front Rise Above Waistline (Jeans, Sweatpants): 6 cm (2.4"), 7 cm (2.8")
Back Rise Above Waistline (Jeans, Sweatpants): 8.5 cm (3.4"), 7 cm (2.8")
Side Rise Above Waistline (Jeans, Sweatpants): 8 cm (3.2"), 7.5 cm (3")

Profile Discretion Rating: 6

The padding on the NorthShore Airlock isn’t among the thickest in the market, but it still leaves a very bulky profile that would be difficult to conceal. I found it had a noticeable diaper bulge at the front and rear. It could probably be helped with meshpants or underwear and appropriate choice of outerwear, but you’d want to take care in making this one discreet. It also has a particularly high rise above the waistline that could easily show without adequate coverage above.

Noise

Noise Rating: 7

I didn’t have any issues with noise when walking around in this diaper and found it to be a lot quieter than the comparable NorthShore MegaMax. It had a little more sound when standing or sitting and I believe that was due to shifting of the thick plastic landing zone. This resulted in a brief crinkling sound. Generally, I wouldn’t expect noise to be an issue with this diaper and it should be easy to cover up with a good choice of outerwear.

Odor Reduction

Odor Reduction Rating: 8

Even though the NorthShore Airlock is cloth-backed, the cloth-backing isn’t particularly breathable or odor permeable, so I didn’t find it to be much different from the MegaMax in terms of resistance to odors. It’s not susceptible to surface dampness and has wide waistbands to assist with odor formation prevention and containment.
