Goodnites Boys XL Protective Underwear Review (3 generation comparison)

 *For more information on how I do reviews see Diaper Test Methodology




If you’ve ever experienced bedwetting you’ve undoubtedly come across “Goodnites Nighttime Bedwetting Underwear”. Goodnites are a uniquely gendered product with separate versions for girls and boys with the most absorbent padding placed in areas most likely to benefit each gender. The Goodnites product is also exceptional in that it bridges the gap between youth and adult incontinence products with a recently added XL size that fits both smaller adults and larger youth. As a protective underwear product Goodnites has a fit that matches what you’d get from regular underwear but includes a rectangular absorbent padding and leak guards for managing bedwetting. To wear or change this protective underwear you simply pull it up/down through your legs. This protective underwear is largely only available in the North American market, but you’ll find a similar product called Drynites in Europe/Australia and some localized versions of Goodnites in places like Korea. Goodnites is manufactured by Kimberly Clark, which also produces the Depend Incontinence line of products for adults and Huggies diapers for children. The only “comparable” product offering in terms of North American market share is a product called Ninjamas, which is produced by Procter and Gamble (P&G), who also produce an Always Discreet line for adult women as well as Pampers diapers for children. But P&G has largely neglected the adult market and the Ninjamas product is unlikely to fit much larger than the average 10 year old, so I wouldn’t call it a serious competitor.

This review marks the beginning of our reviews into protective underwear products, with many more to come in the future, in addition to our regular adult diaper reviews. This review will focus on the Goodnites Boys XL, but the Goodnites Girls XL will also be covered in a followup review for comparison. Also, due to slowness in getting this out, some incorrect purchases and some rapid iterations of the Goodnites product, this review will be covering and comparing 3 different generations of the product. Also covered is a variety of packaging as this product is quite unique in the variations of packaging available. Prior to 2020, the product only had 3 sizes XS,S/M,L/XL but in 2021 the product was split into 4 sizes with XS,S/M,L,XL solidifying its lead over competitors by making a better fitting product for all ages. Then in 2023, Goodnites made further tweaks to its products, introducing a “gap-free” fit and “Quicksorb” technology, which further increased the effectiveness of the product. That said, overall absorbency is still on the lower side and it’s unlikely to be a good choice for full incontinence when compared with adult diapers. The advertised absorbency for Goodnites is "3 water bottles" or 24 oz (710 ml), but in reality I found it came short of that. For practical use, I’ve found the current generation of Goodnites will absorb a single wetting while lying down, but that’s a hard limit and even then you may want additional protection like a booster or plastic-pants. This underwear is highly breathable and durable and in that way it could be a great choice for daily wear. However, it has one major flaw that I feel precludes it from daily wear. That is, the mid-rear padding is rather thin and highly susceptible to pressout, so wetting while seated or sitting shortly after a wetting is almost certainly to result in a leak. So I’d say this underwear is best suited to those with light/moderate daily incontinence and those who only typically only wet once overnight or are otherwise able to change before a second wetting.

Surface Dampness Rating: 6

For its comparatively low absorbency, the Goodnites XL performed surprisingly well when it came to managing surface dampness. During the lab test there was no obvious moisture on the paper towel after the first wetting and only a very small amount after the second wetting. The material over the core padding was clearly designed to prevent moisture from coming back up. However, it does have a major fault, in that if moisture makes it to the rear padding it can feel quite damp and is far more susceptible to pressout. For this reason I don’t rank it as highly as I might otherwise given the lab test results.

Standing-Sitting Rating: 2
The Goodnites Boys L/XL absorbed a full wetting while standing without any leaks. Initially there was significant pooling in the mid-padding, but eventually this was fully absorbed and distributed such that most of the padding was wet. Upon sitting there was a significant leak from the rear padding that appeared rather soon after seated. By this point the padding at both the front and rear were quite saturated. It was clear that the padding, whilst absorbent enough without pressure was not going to hold up to pressout. On the second generation test, the Goodnites XL fully absorbed the first wetting while standing. There was considerable pooling in the mid-padding for the first minute or two after the wetting, but eventually it was fully absorbed. The padding swelled a little, but there was still dry padding at the front and rear. Upon sitting there wasn’t initially any leakage, but after a short while I noticed a small leak below the rear leg gathers so I ended the test at that. Interestingly, the moisture had wicked through most of the padding with the rear padding almost completely saturated and just a little unused padding at the front. Again the padding seems to do a decent job at initial absorption but it is quite susceptible to pressout. On the third generation test with the Goodnites Quicksorb there was no leak while standing. Initially there was significant pooling at the mid section and rear padding while the front was relatively dry, but after a few minutes it was fully absorbed and distributed through the padding. However, upon sitting there was considerable pressout leakage from the rear leg gathers and I ended the test at that. Had there been wicking into the front padding earlier I imagine it would have absorbed a lot more but I still wouldn’t consider this underwear suitable for most daily wear unless you only had light-mild incontinence. I expect this underwear in its current form will manage a wetting while standing but don’t expect it to hold out to pressout or wetting upon sitting.

Lying Down Rating: 3 (2 for previous generations)

The Goodnites Boys L/XL quickly leaked on the first wetting with moisture pooling up in the front, then running under the leak guards and through the wings. This resulted in substantial leakage and it was quite clear that this protective underwear did not provide appropriate bedwetting protection for someone of my size, which makes sense since I was a bit over the recommended weight limit. In spite of this, there was still a lot of unused padding at the rear, so perhaps with better moisture distribution it may still have handled the wetting without leaks. On the second generation test, the Goodnites Boys XL also ended up leaking on the first wetting while lying down, but to a lesser extent. Initially the front padding absorbed everything but soon after there was considerable pooling at the front and some of it made it under the leak barriers and into the left wing before it could be absorbed. This resulted in a small but noticeable leak underneath since the breathable side did nothing to block it or redirect it to the rear padding. After the test all of the front and mid-padding were wet but the rear padding remained dry so had the front leak guards performed better it may have managed the wetting without leaks. For those in the 125 - 140 lb weight range this was still a clear improvement over the previous generation of Goodnites combining L/XL. On the third generation test of the Goodnites Quicksorb XL there was a clear improvement with no sign of a leak on the first wetting while lying down. Unlike the previous two tests, in this test there wasn’t any moisture pooling in the front padding and none made it into the wings. Instead moisture was effectively directed into the mid/rear padding, which felt damp and had initial pooling but eventually distributed it throughout. The dampness lingered at the rear but didn’t escape and there was still considerable unused padding at the front. The second wetting was clearly going to leak but the leak was similar to that on the first wetting with the first generation L/XL with moderate leakage through the rear leg gathers. Initially some moisture did pool up in the front and pushed at the leak guards but they mostly held and the front padding dampened before the excess flow toward the rear. I believe the swelling of the mid padding contributed to more moisture hitting the front on this wetting, with a “damming” type effect. I feel with where this product has evolved the XL should generally manage one wetting without leakage while lying down, but I wouldn’t push it past that.

Daily Wear and Bedwetting

Although the Goodnites Protective Underwear is unlikely to work for most cases of adult incontinence, I feel it was worth a review as it may still be suitable for smaller adults and certainly youths of all sizes. In North America this protective underwear has a major benefit in that you can find it in a large variety of stores and frequently comes on sale, so you don’t have the added complication of dealing with shipping when looking for Goodnites and that could be a great benefit when on the road. In terms of comfort, I found the latest version of the XL to be particularly soft and comfortable. Notably, each version of the Goodnites product has come with two alternating unique designs, each mimicking the patterns of regular underwear even down to a fake fly. There have been significant improvements in Goodnites underwear in recent years with the expansion to XL sizing and work done to improve the fit. That said, I was surprised to find during testing that the weight and padding length were virtually unchanged between the L/XL, XL and XL Quicksorb versions even if the fit noticeably improved. Unsurprisingly, the level of absorbency has hardly changed between versions, with perhaps a slight improvement in the Quicksorb version. I did find the Quicksorb version to be more effective at channeling moisture and a bit faster at absorption, which was likely a major factor in it avoiding a leak on the first wetting. That said, if you’re a heavier wetter this protective underwear is likely to leak. If you fall within the weight range for Goodnites but experience leaks, you may want to try a different product like the Molicare Premium Elastic 10D Small or use the Goodnites product in combination with a booster pad. If used in combination with a booster pad you’ll need to be a bit careful as the width between the leak guards is rather narrow and larger booster pads will likely push out the leak guards, resulting in leaks. Ideally, a leak guard for use with Goodnites will come at a cheap unit price. Although I found I could wear the Goodnites for bedwetting without leaking for several nights, I still didn’t feel super secure in its ability, so I also opted to try it with a booster pad. During testing, I had good luck using Goodnites in combination with Attends Booster Pads, which came at a very affordable unit price but also offered great absorbency and fit perfectly in the Goodnites XL. When I tested Goodnites for daily wear, I found that sometimes the booster pad could be a difference maker in whether it would leak when seated or not. However, in other cases I found it still experienced pressout leakage when seated during daily wear and would still advise against using Goodnites during the day for anything but light/moderate incontinence.

Suitability for Bowel Incontinence: 4

The Goodnites XL wasn’t designed with bowel incontinence in mind and at best I think it might be an OK choice for infrequent light/moderate bowel incontinence. Unlike a diaper, protective underwear will be far messier to change in the case of bowel incontinence since you have to pull it all the way down for a change. It’s also not the best in terms of odor management with its super breathable design and thinner padding toward the rear. The low rise would also pose problems for managing bowel incontinence as it doesn’t have much give in terms of sagging. However, the latest Goodnites Quicksorb XL version does feature good barriers to prevent gaps with the inner leak guards. The inner leak guards themselves are of high quality. It also features a very flexible design with stretchy sides and dual waistbands. Generally I wouldn’t recommend it for bowel incontinence as there are plenty of more suitable products on the market.

Wear & Tear Tests


The Goodnites Boys XL is a protective underwear product with flexible closed sides and rectangular absorbent padding running down the middle. This gives it a fit that’s quite similar to regular underwear. What’s interesting about this protective underwear is that the sides come together into prominent seams on either side where the wings meet. Were it a detachable diaper-like pullup, this is likely where you’d expect to find a fastener. The side material is very strong and stretches at least double its unstretched width. It’s a high quality elastic material and will collapse again when unstretched, but it will eventually lose its elasticity. Additionally, it has both front and rear waistbands, which further aid its stretchiness. It also should be noted that Goodnites has an exceptionally low rise compared with their width. This appears to be by design to aid the discretion of the product so others can’t see it rise above the waistline but I find it can result in the fit feeling a bit precarious. That said, the most recent iterations have steadily improved upon the fitting and I’d argue the latest Goodnites XL Quicksorb product has the best fitting yet.


3.1 Goodnites Boys Fastener (XL Quicksorb,XL,L/XL)


Ease-of-Use Rating: 8 (7 for L/XL)

As an underwear-like product, the Goodnites Boys XL is very easy to use for those in its recommended weight range; you simply pull it up and down as needed. There’s no need to adjust it like you would with a diaper. The elastic fit will adjust snugly to the wearer’s body. That said if you’re bedridden or have a disability that makes it difficult to slide the product on/off then it won’t work as well as a diaper. It also lacks a wetness indicator so it likely isn’t the right choice for use in a caregiver environment. The marketing of the product itself focuses on use for bedwetting rather than daily incontinence so it makes sense that there would be deficiencies if trying to repurpose it more generally for incontinence. On the plus side, there have been substantial improvements with recent iterations of the product. Introducing more granular sizing up to XL then further improving fit with the “gap-free” design makes it far easier to find a Goodnites product that will fit correctly (again for those in the weight range). This puts it well ahead of other similar products like Ninjamas that have only 2 sizes and, as a company appears to have all but given up on larger bedwetters or making meaningful product improvements. The main deficiency I’ve found with Goodnites is that the low-rise can actually hinder comfort, even though it clearly benefits discretion. The width is fine, but I’ve found it often feels like it's sitting a bit too low and needs to be pulled back up. Though, that’s less a concern during the night where it's more likely to hold in place.


3.2 Goodnites Boys Fit (XL Quicksorb, XL, L/XL)


Comfort Rating (dry): 9 (8/7 for previous generations)

The Goodnites product has steadily been improving in recent years and I found the third generation Quicksorb to be the most comfortable yet for dry wear. The main differentiator being that the leak guards/leg gathers are a bit softer and fit snugly between the legs. Goodnites advertises this as a gap-free fit and I can attest that the previous generations of the product were more susceptible to gaps between the wearer’s legs and the inner leak guards. Overall, the materials feel a little softer in the Quicksorb compared to previous generations, the materials also feel a bit more flexible. The padding itself is quite durable and I never really had issues with clumping or tearing, though the actual area of coverage is somewhat lacking in the mid-section. Goodnites has a very breathable design and I never had issues with overheating or discomfort and it could be an excellent product for warm weather wear. In terms of sizing, there was a noticeable improvement when the existing L/XL was split into separate L and XL sizes. I give both the XL versions a rank higher in comfort because of this (sizing availability is all the more important for a product that isn’t adjustable in the way you’d get with diapers). For someone with relatively large hips I found the XL fits perfectly comfortable compared with the old L/XL. Aside from widening the somewhat narrow mid-padding, the only other thing I feel would make the Goodnites XL better from a comfort perspective would be a slightly higher rise since it has quite a low rise. That said, I feel that’s more of an issue when wet and the weight pulls it down; the fit is comparable to what you’d get from any lowrise underwear and understandably provides discretion.

Comfort Rating (wet): 8 (7 for L/XL)

I found the third generation Goodnites Boys Quicksorb to generally be more comfortable when wet compared with previous generations. With the caveat of its limited absorbency, I put it slightly above average in this category. This protective underwear is highly breathable and I didn’t notice much difference between its wet and dry state during overnight wear. However, this is dependent on how large a wetting it receives/how moisture is distributed, given the limited absorbency. The overall amount of padding is pretty limited with much of the absorbent material in the front/middle padding and much less at the rear. When the front padding captures moisture it swells but remains relatively dry/comfortable, but I found if any moisture makes it to the rear padding it will feel noticeably damp. With its better leak guards and faster absorbing padding, the third generation protective underwear is less likely to have damp rear padding than the previous generations. Also, the padding proved quite resilient and I never noticed an issue with clumping or tearing, nor did I have much issue with sagging (though previous generations tended to sag a little more after extended wear, whether wet or dry and weren’t as good with moisture-redirection). Once again, the low profile detracts a bit from the comfort of this product; even if the fit holds up, it always has a feeling like it’s about to slide off, particularly with the extra weight when wet.

Shake Deterioration Test: 3 shakes to deterioration

Durability Rating (dry): 9 (8 for the L/XL)
The Goodnites Boys XL proved highly durable during testing. During the dry durability tests there was never much in the way of padding deterioration and everything that did occur was outside of the core padding (albeit the core padding is a bit thin toward the mid-section). In terms of the sides, they held up without tearing in each model. However, I have accidentally ripped the L/XL very by pulling it up too quickly. I was clearly a bit oversized for that underwear, but I rank it lower than the other two because the granular sizing makes that less likely to find a proper fit in any size. In both the previous XL and L/XL versions I also noticed that sometimes the cloth-like fabric can loosen from the underlying plastic above the padding. Because the cloth here is more of a superficial feature with no impact on performance and it never tore much anyway, I didn’t count this as a fault toward overall durability. Other than that, because of the way the seam sits at the side I wouldn’t recommend pulling at it near the seam even in the XL versions. There’s a natural point in the structure where the seam is thinner and if pulled too hard it can start to come apart. I didn’t find sagging to be an issue in the Goodnites dry state, particularly in the XL versions, which held their form particularly well. I’ve tested it pretty extensively and I’m confident this protective underwear will hold very well during daily wear and even during more intense exercise. I’d highly recommend it for that purpose for those who don’t find the absorbency to be too light.

Durability Rating (wet): 8 (7 for the L/XL)

The Goodnites Boys protective underwear demonstrated strong performance in terms of wet durability. I didn’t find any difference from its dry durability state. There was no significant clumping or tearing and the core padding remained well intact. That said, the middle padding is not very wide to begin with so any amount of deterioration here, even at the edges, can affect absorbency. Additionally, in this type of protective underwear the sides can become overstretched and lead to some sagging, but personally, I only found that to be an issue in the L/XL; so it likely has more to do with the product being undersized for the individual (myself being above the recommended weight-range for the L/XL). In any case, I rate the latest two versions of the product better than the previous version as the more granular sizing makes it easier to achieve a good fit and less likely to encounter durability issues. All in all, the Goodnites wet durability is unchanged from its dry durability.

Profile Discretion Rating: 10

The Goodnites Boys XL gets top marks for profile discretion. This underwear was explicitly designed to be discreet. You’re unlikely to catch a hint of rise above the waistline as it has a very low rise, the patterns are quite subtle, and the fit is snug with the relatively thin padding meaning no bulge is likely to appear. It might be noticed under very tight fitting clothing, but even then I think it could generally be kept discreet. It’s highly unlikely for anyone would ever notice someone wearing Goodnites.

Noise Rating: 10

The Goodnites XL also gets top marks for its noise discretion. It doesn’t have tapes so you wouldn’t get any noise from that, but also the soft flexible material seems to absorb noise and I wasn’t able to detect any obvious noise from this underwear when sitting, standing or walking. It’s about as quiet as you could possibly hope to get for incontinence protection.

Odor Reduction

Odor Reduction Rating: 5
I don’t find the Goodnites XL to be particularly strong when it comes to odor reduction. Part of this is likely because the breathable design also makes it a little more likely to release rather than contain odors. The snug fit counters that somewhat, but not entirely. But I think the big issue is that the mid and rear padding are more susceptible to surface dampness and that results in odor formation. I rank this protective underwear right around the middle of the range in this regard and were the core absorbent padding a bit more extensive I suspect it would do better.
