Summary

Our previous review of the NorthShore MegaMax continues to be among the most popular reviews we’ve done in the blog. NorthShore released the ultra-high absorbency MegaMax diaper in 2018 and has iterated on it multiple times over the years. Since launch, NorthShore has added a number of different backsheet patterns for those who like a little variety beyond plain white diapers and they’ve also introduced a lite version for daily wear. I first reviewed the MegaMax back in 2021 and was impressed with the overall absorbency. It was a particularly notable standout among ultra high absorbency diapers emerging at the time due to its exceptional resistance to surface dampness. Initial production runs of this diaper were produced in China, but in more recent years NorthShore has pulled some production closer to home. This makes it easier for the company to oversee production and manage costs/delivery times. In the American market they’ve introduced a new version of the NorthShore MegaMax, which I’ll refer to as the NorthShore MegaMax USA. It’s impressive to see a company that is so involved in the production process, where many of their competitors simply import small variations on what is effectively the same product with different branding. It’s currently in its second major iteration and NorthShore was kind enough to provide some packages for this review. I expect many further improvements with future iterations and I’ve learned from NorthShore that this version will soon have a softer, quieter backsheet that matches the original Chinese version. It will also drop the wetness indicator to match the original, as many prefer the added discretion of no wetness indicator when a wet high absorbency diaper is obvious from swelling or other factors alone.

As it stands, this is likely the most absorbent diaper currently made in North America. I found that idea particularly interesting because the last US-made high absorbency plastic-backed diaper that we reviewed was the ConfiDry 24/7 and it was sad to see that great product fail to meet its market potential. This also marks the first time we’ve effectively re-reviewed a previously reviewed product. Re-reviews are typically a challenge because products change all the time, sometimes even batch-to-batch in the same production run. There isn’t enough time in the world for a small blog like this to keep on top of such changes. But I felt it was quite warranted for this particular model due to the substantial shift in production that NorthShore is undertaking to bring it to market. In fact, I’ve even started going back to backfill the medium size into the previous review, since initially I only reviewed the small size and medium is better aligned with my standard review sizing comparison.

Having said all that, there weren’t any huge surprises during my review of the NorthShore MegaMax USA. Absorbency was comparable with the lab test results for the medium size being virtually identical. In real world testing it may have been slightly less absorbent when lying down and slightly more absorbent during daily wear. In both cases I’d expect 2~4 wettings before leakage would typically be a concern. Both versions of the diaper have a very wide, slightly stiff padding that provides exceptional surface dampness once moisture is locked in, but can be slow to absorb. This creates the potential for some premature leaks when a padding fold pushes moisture to pool too much near the leak guards. I also noticed moisture hanging around the leak guard a bit more in this diaper than the original MegaMax. I couldn’t figure out exactly why that was the case, but my best guess is that the wider initial fold of this version made it a bit easier for moisture to reach the edges (note the folded width of 19 cm (7.5”) vs 17.5 cm (6.9”) in the original). I expect this may be less of an issue in future production runs, but it’s something to watch out for. Otherwise, my measurements comparing the original and USA version of this diaper all came out virtually identical. The company is quite receptive to concerns when issues are discovered and I’m confident that this will continue to be a great choice for anyone with heavy incontinence.

Surface Dampness Rating: 9

The NorthShore MegaMax USA performed incredibly well during the lab surface dampness test. There was little-to-no sign of surface dampness during the first 3 wettings and it wasn’t until the 5th or 6th wetting that it really became noticeable. This matches the great performance of the original in that regard. Once again, the only reason I can’t give this a perfect score is that in real world wear you’re likely to notice pooling during a wetting. I believe the same great material that keeps surface dampness locked away also can slow absorption, so it’s a bit of a trade off. Otherwise, this diaper does a great job at repelling pressout.

Standing-Sitting Rating: 8

The NorthShore MegaMax USA was a strong performer when tested while standing and sitting. I first tested the medium. It easily absorbed the initial wetting while standing and moisture was quickly distributed through the padding. Moreover, there was no sign of leakage or pressout upon sitting shortly afterward. The diaper felt comfortable and surface dampness wasn’t particularly noticeable. There was still a lot of dry padding at the front and rear of the diaper. On the second wetting while seated moisture pushed back up the front of the diaper a little and dispersed through the dry padding. The diaper easily handled the wetting without leaks and the padding swelled significantly. Even though there were no leaks I did notice some slight dampness around the leg gathers, so it’s possible some moisture made it around the inner leak guards. The third wetting was quickly and easily absorbed with moisture pushing up the front then back into the padding. The padding is quite wide and I believe as it became softer with the dampness it was able to wick a little better on this wetting. Interestingly I didn’t notice the moisture around the leg gathers at this point and there was still a lot of dry padding at the rear of the diaper. There was no sign of any leaks at this point, so I continued the test. On the fourth wetting moisture was dammed by the thick mid-section padding and mostly pushed back up into the front of the diaper where it pushed against the leak guards. Some moisture made it through the leak guards into the wings but ended up settling in the rear padding. There weren’t any obvious leaks but the front of the diaper was clearly at capacity and had the wings not been moisture impermeable it certainly would have leaked by now. It did seem like a small amount of moisture was able to make it to the outer side of the leak guards, but was still trapped by the leg gathers so no leaks were obvious. Eventually that subsided and wasn’t noticeable. On the fifth wetting moisture again quickly pooled in the front and pushed through the leak guards. This time enough escaped the leak guards to result in a small leak and I ended the test at that, as it was clearly saturated. Most of the rear padding was still dry at this point, so with channeling there was potential for much more absorbency. I tested the large size next; it was clearly too large for me but I wanted to get a sense of its performance regardless. Again, the first wetting was easily handled without any signs of leakage and limited pooling. As expected, there was no sign of leakage upon sitting shortly afterward. The second wetting while seated again was easily handled. This time there was a bit of damming from the swollen mid-section padding. More moisture pushed up into the front padding and absorption was a little slower. But with the huge amount of padding to spread through it was comfortably absorbed without any sign of leaks. The third wetting was also easily absorbed. This time moisture pushed further up the front padding due to the mid-padding damming. There was a bit more pooling but it was again easily absorbed through the abundant padding. There was no sign of leaks at this point but much of the front padding was wet. The fourth wetting continued to result in moisture pooling and pushing up the front padding. Eventually some made it through the leak guard and escaped into the front wings where a little was able to produce a leak at the bottom. The front padding was clearly soaked but the rear padding was completely dry and it surely would have absorbed more with better channeling, but that’s a pretty common challenge for these ultra high capacity diapers. I’d generally expect this diaper to absorb 3~4 wettings with daily wear and perhaps much more if you tend to wet more when standing than seated.

Lying Down Rating: 8

The NorthShore MegaMax USA also performed decently when tested while lying down. Again I started testing with the medium. The first wetting was easily absorbed with moisture quickly sinking into the mid and lower rear padding. I didn’t notice much in the way of pooling and surface dampness quickly subsided. The second wetting initially performed quite well but there was more obvious pooling on this one. Moisture moved into middle and rear padding where it quickly distributed. However, some pooling had pushed up against the inner leak guards between the legs and some escaped into the leg gathers where it resulted in a small leak. I ended the test at that even though there was still a significant amount of dry padding at the front and rear and the padding clearly could have taken more. Considering the volume absorbed across the two wettings I’m pretty certain it would absorb more with a number of smaller wettings. The width or flexibility of the middle padding may have partly contributed to the early leak as wide padding diapers like this can sometimes fold between the legs and push moisture outward toward the leak guards before it can be fully absorbed. Next I tested the large size. The first wetting was similar with moisture quickly sinking into the middle padding and distributing until it was fully absorbed. Again there was little pooling or surface dampness afterward and no signs of leaks. The front and rear padding remained almost completely dry. On the second wetting moisture again sank to the same area and there was a bit more in the way of temporary pooling. It was fully absorbed without any signs of leakage, but I did feel a little dampness around the leg gathers. On the third wetting moisture pooled quickly in the mid-section and started spreading up the rear padding. There wasn’t an obvious leak initially, but after not-too-long I noticed a small leak around the leg gathers and the leg gather area was again noticeably damp. Depending on the size of your wettings and fit this diaper should absorb 2~3 wettings while lying down and potentially many more smaller wettings.

Daily Wear and Bedwetting

The NorthShore MegaMax USA made for an interesting review, particularly because I had some of the original version left to test and compare with directly (both in medium). This made it easier to do a direct comparison between the two versions rather than relying solely on memory. Moreover, the first time I tested this diaper I went with the small size because it seemed most aligned with my measurements. This time I went with the medium to allow for a better comparison with other reviewed diapers on a standard size. I tested this one in large as well because I had the size available, but that sizing was clearly too big for my fit, so take those results with a grain of salt. I’ve also been revisiting my original review to backfill the stats and findings on the medium sized diaper. The dimensions between the USA version of this diaper and the original were nearly identical with only subtle changes that would not have any real impact on performance. Both the new USA version and original are the same weight and about the same length and thickness. Upon opening and comparing both versions the most immediate difference I found initially was that the folded width on the original is narrower, causing the original to feel a little denser and more compact. The next noticeable difference was that the backsheet on the original was smoother than the USA version and this new version had a wetness indicator, which was lacking in the original. This made the original version feel a little more comfortable in comparison, though I still found the USA version quite comfortable. After correspondence with NorthShore I learned that they will soon be dropping the wetness indicator and going with a smoother, softer backsheet to match the original, so I don’t expect this difference to hold for much longer. In terms of performance I found the two versions to be quite comparable. For absolute capacity they are virtually identical. In real world testing performance varied, with the original perhaps performing better in overnight wear and the USA version maybe a little better in daily wear. My biggest concern with the USA version in comparison to the original was that sometimes I noticed more moisture in the inner leak guard area around the leg gathers. I couldn’t quite figure out why that was the case. My best guess is that it had something to do with the fold structure and padding condition in that mid-section. Alternatively it could be that there was a weakness in the moisture resistant topsheet at the edges that may have allowed more moisture to escape. It was also only really noticeable after heavy wettings and with lighter wettings the two versions felt about the same. The padding construction of each is very similar with a dense honeycomb-like padding. The topsheet is highly resistant to surface dampness and pressout, but both versions of this diaper have the same challenge with slower moisture acquisition. The combination of a wide mid-section padding and relatively slow moisture acquisition means pooling can form during heavy wettings and mid-section swelling/inward padding folds can redirect moisture out toward the leak guards. If the pooling is significant enough then you will get leaks through the leak guards well before the diaper has reached capacity (usually after 2 or 3 wettings). With smaller wettings this is less of a concern and in ideal circumstances you might expect 5 to 6 wettings before leakage would be a concern. The leaks, when they happen, tend to be small so you could potentially mitigate them and extend the life of the diaper a bit longer by combining it with a diaper cover (plastic pants). For most wearers I believe this diaper will be a great choice for daily wear and bedwetting and continue to recommend it for both purposes. I’m looking forward to seeing how NorthShore iterates on and improves this diaper over time now that they have more production oversight. As of now, I can’t see a compelling reason to rate this diaper any different than my ratings of the original.

Suitability for Bowel Incontinence: 8

The NorthShore MegaMax USA is well suited for managing bowel incontinence, having all the key features you’d want in such a diaper. There’s a large amount of rear padding and the padding coverage is quite wide. It has well placed standing inner leak guards for containment. The plastic backsheet and waistbands make it quite suitable for odor containment. Slower absorption rate could be an issue and again the leak guards aren’t the strongest on the market (still quite good though).

 

Wear & Tear Tests

Fitting

The fit of the NorthShore MegaMax USA is effectively the same as the original. Both diapers feature a plastic backsheet with a special landing zone for tape placement. Tapes can be refastened to this landing zone multiple times without losing their adhesiveness. In both versions the tapes have a very strong grip so you need to be careful how you pull at them. The sizing of these diapers is more aligned with North American sizing than the NorthShore Supreme line, which has more European sizing. I found the medium to fit a little on the large size. The only real notable difference I found between this version of the MegaMax and the original was a wider folded width on this one. However, the unfolded width and padding width was slightly less.

Ease-of-Use Rating: 8

As far as ease-of-use goes the NorthShore MegaMax USA is pretty much identical to the original. It’s quite easy to obtain a snug fit with this diaper and it’s full featured with dual waistbands, stretchy leg gathers and inner leak guards. The refastenable landing zone is a big plus, making it easy to re-attach tapes if you need to make adjustments or when toilet use is possible. The version I tested has a wetness indicator, which could be helpful for caregivers. But I didn’t weigh that heavily as it will be removed in future batches. Once again, the biggest potential challenge many will find with this diaper is that the tapes have a very firm grip. It’s great for keeping them from sliding off, but some may struggle to remove them when it’s time for a change or an adjustment is needed. Additionally, compared to the first time I reviewed the MegaMax the packaging has improved considerably with far more information. It provides a detailed sizing guide with recommended waist/hip measurements as well as a weight based measurement.

Comfort

Comfort Rating (dry): 9

I couldn’t find a compelling reason to rank this diaper any different from the original NorthShore MegaMax when it came to dry comfort. This is particularly since NorthShore will soon be making changes to the diaper that bring it even closer to the original design (same backsheet materials that made the original feel soft and comfortable). I would say compared to the new USA version the backsheet materials on the original feel a bit smoother. Both diapers share a near identical design and fit with landing zone placement and tapes. Notably they both have nearly the same honeycomb-like padding structure. The materials used are soft and I actually found the topsheet on this one to be slightly softer/less compact than the original. It’s soft, but not the softest on the market. They provide a relatively breathability for a plastic-backed diaper, though you won’t get nearly what you’d get from a cloth-backed diaper in that regard. On the plus side, the padding is highly durable and doesn’t clump or tear during wear. So you won’t get any discomfort from material deterioration after extended wear. You can also be highly confident that this diaper wouldn’t dare ever loosen or sag during wear.

Comfort Rating (wet): 10

When it comes to wet comfort I continue to rank the NorthShore MegaMax USA the same as the original (and other NorthShore products for that matter). The topsheet material they use is incredibly resistant to dampness and pressout moisture. The only real potential issue is pooling due to slow acquisition but I consider that a temporary state that doesn’t impact actual wet comfort. The padding on this diaper easily continues its durability when wet with no obvious clumping or tearing in this state. Moreover, the tapes will hold an incredible amount of weight and you’ll never notice much in the way of loosening or sagging when wet. As far as wet comfort goes the NorthShore MegaMax USA earns top marks.

Shake Deterioration Test (M): 4 shakes to deterioration
Shake Deterioration Test (L): 3 shakes to deterioration

Durability Rating (dry): 8

The NorthShore MegaMax USA was a very strong performer when it came to dry durability. I noticed very little deterioration during the dry durability test and much of that was due to the extra wide padding collapsing inward a bit between the legs. Core padding remained strongly intact and there was no sign of clumping or tearing after durability testing. The tapes hold strongly almost to a fault as they can be difficult to remove. But this is what you want for a diaper that’s never going to come loose on you. Like the original, you need to be a bit careful about pulling too hard on them to remove them as you can inadvertently damage parts of the backsheet. I found the tendency to damage the backsheet by pulling tape too hard was more of an issue on the original than the USA version. These are bulky, but if you need the protection they could be used for active wear.

Durability Rating (wet): 9

The NorthShore MegaMax USA demonstrated strong performance when tested while wet. The padding conditional was little changed from its dry state, with no additional deterioration. The honeycomb-like padding is the same as the rest of the NorthShore MegaMax line of products. It’s pretty dense but tends to swell and soften a bit when wet. Yet it stays firmly in position between the backsheet and the topsheet. This one performed about the same as the original in the wet shake test, but I don’t weigh that test very heavily in terms of durability. The tapes on this diaper are incredibly strong and you won’t ever have much for sagging or loosening due to tape weakness. They can hold a tremendous amount of weight that far exceeds what the diaper can absorb.

Profile Discretion Rating: 6

The NorthShore MegaMax USA like the original is not designed for discretion and instead prioritizes absorbency. Consequently it’s quite thick and produces a noticeable diaper bulge under most outfits. Again, it’s not as obvious as some diapers on the market, but you will need to take great care to conceal it.

Noise

Noise Rating: 5

The NorthShore MegaMax USA is about the same as the original when it comes to noise discretion, perhaps a little noisier (but with the upcoming changes I doubt it will be any different). Again, the most prominent source of noise is the thicker plastic tape landing zone at the front of the diaper. The backsheet material itself doesn’t produce much noise in comparison and the two should be identical on the next iteration when the materials match.

Odor Reduction

Odor Reduction Rating: 8

Both the NorthShore MegaMax USA and original have a padding that’s highly resistant to surface dampness. They also both feature a plastic backsheet and snug design with solid dual waistbands. You’re unlikely to notice odors from this diaper and it continues to rank high in this regard.
