Summary
This review covers another remarkable iteration of the Goodnites line of products, which recently released an XXL version sized for those in the 120-165 lbs (54-75 kg) range. This marks the third major iteration of the product over the past several years. In 2021 the product range increased from 3 sizes to 4 with the introduction of the Goodnites XL. Later, in 2023 Goodnites made further tweaks to the XL to improve the leak guards and create a better fit (I’ve referred to it as the Quicksorb version). Finally, this past April they released a new size XXL and the sizes range has grown to include: XS, S/M, L, XL and XXL. This is far more extensive than any competitor product and now covers youths from 28 lbs (12.7 kg) all the way up to 165 lbs (75 kg), fully bridging the gap between youth and adult products. If you’ve ever experienced bedwetting you’re almost certain to have come across these, and, while these are geared toward the youth market, the upper end of the range will almost certainly fit smaller adults. In a previous review, I covered the Goodnites XL and found it to be reasonably absorbent for a protective underwear, but a little short for what would be needed for someone of my size (I was at the top of the suggested range in that product ~140 lbs). It looks like that size has been relabeled and now rather than a suggested weight range of 95-140 lbs+ (43-64 kg+) has a suggested range of 95-120 lbs (43-54 kg). However, as far as I can tell, the dimensions haven’t changed and the findings from the previous review should still be relevant.Goodnites are a gendered product with different zones of absorbency per gender. For this review I’ll be covering the boys version, which I previously found to be a little more absorbent than the girls version. These are a protective underwear product that can be pulled on/off like regular underwear, but contain a rectangular absorbent pad down the middle. With previous versions of Goodnites I’ve found the rise to be relatively low and I chalk that up partly to their needing discretion, though at the cost of some comfort. The Goodnites XXL have a notably higher rise compared with other versions and should work better for taller individuals. This underwear has also been notable for its variety of backsheet designs and typically features two designs per size, though interestingly the XXL size only has a single design per side; I suppose it's a factor that becomes less relevant for those in this larger size range. Sizing aside, I generally found this to be the same product as the smaller Goodnites. It has many of the same advantages including its comfortable, durable and discreet design. But also some of the same faults, including narrow mid/rear padding and susceptibility to pressout moisture (particularly upon sitting). I do feel the absorbency puts this product to a state where it could generally manage a single wetting without leaking within the size range, at least based on my own experience. However, I wouldn’t completely trust it and recommend using it with a booster pad and diaper cover, particularly if you can’t change out of it before sitting down in the morning. It could also be very effective in daily wear for those with light/moderate incontinence. In any case, it’s great to see a large company moving so quickly with these product iterations and I suspect this won’t be the last of them.

Surface Dampness Rating: 5
The upscaling of the Goodnites sizing to XXL didn’t have any obvious impact on its performance with respect to surface dampness. It performed relatively well for its absorbency in the laboratory paper towel test, with no obvious dampness after a single wetting but a modest amount present on the second. The front material seems to have some particular resistance to surface dampness, but the middle and rear padding are quite prone to dampness and pressout.

Standing-Sitting Rating: 2
When tested while standing and sitting the Goodnites XXL performance was pretty similar to previously tested Goodnites products. In all cases absorbency was far less than lying down, largely due to pressout when seated. When wet while standing there was initially some pooling around the crotch with some pushing up toward the lower front leak guards and much pooling in the less absorbent mid-padding. I felt like it was close to escaping the leak guards but managed to stay within them. There wasn’t any hint of a leak. There was still a decent amount of dry padding at the front of the protective underwear and even a bit at the rear, but the mid-section padding was completely saturated. Upon sitting shortly afterward there wasn’t an immediate leak, but eventually modest leaks developed through the rear leg gathers with pressout, so I called the test at that. So although the Goodnites XXL is generally more absorbent than other versions, its padding isn’t constructed in a way that will prevent pressout leaks from sitting (the weakest padding is in the area most susceptible to pressout when seated). You’d want to use this underwear with a booster pad for daily wear or, alternatively, it could be used for moderate leaks or maybe mild bowel incontinence but shouldn’t be used for full wettings.

Padding to Absorbency Score: 1.47 ml / cm2 (0.34 oz / in2)
Lying Down Rating: 4
The Goodnites Boys XXL performed relatively well when tested while lying down, absorbing more than any other Goodnites product tested so far. The first wetting was fully absorbed without leaks, though the rear padding did feel pretty saturated afterward. Initially there was notable pooling with a significant amount of moisture making it toward the less absorbent mid and rear padding. This had me concerned that there could be leaks, but surprisingly it was all absorbed. The front of the protective underwear also retained a bit of dry padding toward the top, suggesting slightly more absorbency potential. I took an intermediate measure of the amount absorbed and it came out to 500 ml (16.9 oz), so it should be able to manage a larger wetting without lying down. The second wetting was clearly going to leak but I gave it a test anyway to see how the end capacity would compare against previously tested Goodnites versions. As expected there was significant initial pooling with moisture moving both up the front and toward the rear. There was a significant leak under the rear leg gathers and a modest leak as moisture pushed past the front leak guards/escaped below the wings on the sides. Clearly this protective underwear will only manage a single wetting while lying down and shouldn’t be pushed beyond that, but it will provide slightly more absorption than the previously tested XL and that could prove the difference in making it reliable enough for some to use it for managing bedwetting, where the Goodnites XL came out just a little short.

Daily Wear and Bedwetting
The Goodnites XXL was a considerable step up from the Goodnites XL in terms of sizing and a modest step up in terms of absorbency. At its core, this is the same youth protective underwear and its unit weight is only about 10g (0.35 oz) more than the comparable Goodnites XL, so it was never going to perform as well as a high absorbency adult diaper. Nevertheless, I found the fit on this underwear to be just about perfect and very comparable or only slightly smaller than the Depend Real Fit S/M sizing. With the ultra-stretchy sides on these, I’m almost certain they could be feasible for some people above the 165 lbs (75 kg) maximum suggested weight range. These have the same nice features you get in the smaller sizes, including dual waist bands and generous leak guards. The front padding on this protective underwear runs all the way to the top of the underwear and very effectively wraps the male anatomy. I tested these for real world bedwetting and, for nights where I only wet once, they could generally manage a full wetting without leaks, but I never had full confidence in them and doubled up on protection to protect my sheets. I’d generally recommend combining them with a booster pad and diaper cover if you want to be confident they won’t leak, particularly if you’re a heavy wetter. I also found that, more often than not, the upper front padding would remain dry, so the absorbency would fall short of its theoretical level. Though the high rising front padding will work better for certain sleeping angles, so it’s not without benefits. I noticed this tendency for dry front padding a lot more than in the lower rising Goodnites XL. Ironically this padding position could make the product better for daytime wear, where it may be comparable to the function of the Depend Real Fit, but with better leak barriers and more overall absorption. However, I can’t recommend these for daytime wear because I very consistently got leaks through to mid/rear leak guards if sitting when wet, even when the underwear was well below capacity. The adjacent section of padding has very little effectiveness in retaining moisture and is probably the biggest outstanding issue that, if solved, would make Goodnites a well-rounded solution for day or night. For nightly wear this pressout is less of an issue because you’re unlikely to generate enough pressure when lying down to cause pressout moisture to escape the leak guards (pressure tends to be more evenly distributed). This underwear was also incredibly durable and I found I could wear it just like regular underwear to walk, run or do other activities without worrying about deterioration and being fairly confident of its discretion. So if the level of absorbency works, it could be a good choice for more active individuals and warm weather wear.Suitability for Bowel Incontinence: 4
Goodnites are designed for bedwetting as a primary function and aren’t particularly well suited toward bowel incontinence. This applies to the XXL just like it did to the XL. They could still work for light/moderate bowel incontinence because they have some features that are helpful for it. These include standing inner leak guards and strong leg gathers. However, these being a protective underwear, they’re not going to be well suited for smooth changes. The breathability could also introduce odors. The narrow mid/rear padding and potential shifting could also be an issue. There are certainly better products on the market to deal with this condition, but I have thought these could be a good first line of defense for those with infrequent, unpredictable and disruptive bowel episodes.
Wear & Tear Tests
Fitting
The Goodnites Boys XXL is a protective underwear product with flexible closed sides and rectangular absorbent padding running down the middle. The fit is similar to regular underwear and it has a highly elastic design. These are effectively a scaled up version of the Goodnites XL Quicksorb, with a total length of 68 cm (26.8) in the XXL vs 60 cm (23.6) in XL (a 12% increase in length) and 55 cm (21.7) vs 48 cm (18.9) (a 13.6% increase in length). The total brief area of 1,864 cm2 (289 in2) comes out to be nearly identical to the S/M Depend Real-Fit Maximum at 1,891 cm2 (293 in2) but with significantly more padding coverage. This underwear has a gender specific design with its most absorbent padding taking 29 cm (11.4”) up the front of the underwear, stopping just short of the waistband. The padding stops a bit short at the rear, but still extends further back relative to the Depend Real-Fit. This underwear also features the light blue standing inner leak guards of Goodnites Quicksorb XL version. The rise up the waist on this underwear is notably higher than the Goodnites XL and I actually found it had a slight rise above my pant level where the XL version typically stayed below it. However, in spite of its increased length, the middle-width in this underwear is nearly identical to the Goodnites XL and even comparable to the much smaller Pull-Ups 5T-6T. I sit right near the middle of the recommended weight range for these and found the fit nearly perfect if not slightly large. If you found the XL version even a bit large then these will be too large for you.

Ease-of-Use Rating: 8
I rank the Goodnites Boys XXL the same as the Goodnites Boys XL in terms of ease-of-use, if anything the further expansion of the Goodnites sizing range makes it easier than ever to find a proper fit. With this addition, Goodnites now features 5 different sizes for weights as small as 28 lbs (12.7 kg) to as large as 165 lbs (75 kg). Once again, the way you use these is pretty simple. Pull them up to change into them and pull them down when they’re wet. These have a highly flexible design so there’s no need to make adjustments and they will snugly fit the wearer’s body so long as you’re within the recommended weight range, which for the XXL is quite generous at 120 - 165 lbs (54 - 75 kg). They also have a convenient label at the back to distinguish the front from the back. Of course this underwear type design won’t be ideal for caregivers and this protective underwear lacks a wetness indicator, so the padding swelling would be the only way to notice when it's wet. That said, Goodnites are marketed first and foremost toward youth bedwetting and consequently the deficiencies might be expected if using it more generally for incontinence. I found they have general deficiencies in terms of pressout moisture when worn daily due to the weaker mid-section padding. If you’re using these for bedwetting and the absorbency is within your needs then these are about as easy a product as you could ask for.

Comfort
Comfort Rating (dry): 9
I’m sticking with the dry comfort rating I gave to the Goodnites XL Quicksorb when it comes to the XXL version. These products are effectively identical when it comes to structure and materials. For me personally, I’d say these were even slightly more comfortable, with the more generous sizing and waist rise whereas the rise on the XL felt a little lower than my ideal. These have a form-fitting design with extensive elasticity and highly breathable material construction. Like the Goodnites XL, the main deficiency in terms of comfort is the relatively narrow mid-section padding. Due to the narrowness of the mid section it can be prone to shifting and ending up in awkward and potentially uncomfortable positions. Even so, the padding is highly resilient and doesn’t easily clump or tear. Aside from that, the front padding on these has a noticeable thickness, yet it’s also incredibly soft. I noticed the thickness of this protective underwear a little more than with the XL, but I wouldn’t say it had a negative impact on my perception of comfort. Overall, this will generally be about as comfortable as regular underwear when dry.
Comfort Rating (wet): 6
The Goodnites Boys XXL has conflicting attributes when it comes to wet comfort. The front padding is generally moisture resistant and won’t feel too different when wet or dry. However, the mid and rear padding have notable surface dampness issues and are quite susceptible to pressout moisture. So depending on which part takes the bulk of the wetting, it will feel either damp or dry. I noticed this more in the Goodnites XXL than the Goodnites XL. I’m not sure why, but I suspect it might be due to the slightly different distribution of padding, with the most absorbent padding sitting relatively higher on average. I also found that the Goodnites XXL could sag a little more than the Goodnites XL, but that’s likely more due to the looser fit for me personally and not something inherently different with this size. Aside from that narrow stretch of mid-to-rear padding, this underwear continues to remain highly breathable when wet and the padding remains well intact. So this protective underwear is hardly the best in terms of wet comfort, but it’s still far from the worst.

Durability
Dry Padding Deterioration Proportion: 7.9% (topsheet), 8.3% (backsheet)
Shake Deterioration Test: 3 shakes to deterioration
Durability Rating (dry): 9
The Goodnites Boys XXL has a highly durable design and is one of the products I’d feel most comfortable exercising in. This is due to the highly elastic structure and relatively well-bound padding. I hardly noticed any padding deterioration in these after walking and running. Even the minor deterioration noted was only due to a bit of peripheral padding collapse and not impactful on the core. These have a prominent seam on both sides where the two wings are connected, but I never noticed any weakening during testing. However, I wouldn’t recommend pulling at the seam because too much of a pull could start to pull them apart. Aside from that, I never had much issue with sagging while dry in this protective underwear, but the sides can stretch slightly with extended wear. Overall, these are well suited for active wear so long as the absorbency is sufficient.
Durability Rating (wet): 8
The Goodnites Boys XXL is pretty much identical to the Goodnites Boys XL when it comes to wet durability and again not far off the dry durability. I didn’t notice any significant clumping or tearing of the core padding when wet, though the middle padding isn’t too wide to begin with so any amount of deterioration can have some impact. The sides on these also can become a bit overstretched with wear; this can be more notable when wet and may lead to a slight sag, though there have been material improvements to this vs the pre-Quicksorb generations.

Discretion Tests
Profile
Front Rise Above Waistline (Jeans, Sweatpants): 2 cm (0.8"), 2.5 cm (1")
Back Rise Above Waistline (Jeans, Sweatpants): 0.5 cm (0.2"), 0 cm (0")
Side Rise Above Waistline (Jeans, Sweatpants): 1 cm (0.4"), 2 cm (0.8")
Profile Discretion Rating: 10
The Goodnites Boys XXL is generally similar to the XL in terms of profile, but I felt like I noticed the padding thickness a little more and the rise above the waist was present, whereas XL didn’t show any rise above the waistline. I consider this to be a bit of a borderline 10 score, at least relative to the XL, but it will still have a much more discreet profile than most adult diapers. Also, I fit the middle of the weight range for this underwear whereas I was right at the top for the XL so this may be more representative of the score. If anything, it’s comparable with the Depend Real Fit with regards to profile discretion.

Noise
Noise Rating: 10
The Goodnites Boys XXL gets top marks for noise discretion. I never noticed any noise from this protective underwear whether seated, walking or even running. The soft, flexible material and cloth-like backsheet seem highly resistant to making noise. Even under lighter clothing it’s unlikely anyone will notice any sound from you wearing these.

| 4.3 Goodnites Boys XXL Noise Profile |
Odor Reduction
Odor Reduction Rating: 5
The material construct of the Goodnites Boys XXL isn’t any different from any of the smaller Goodnites products and consequently it has the same susceptibility to odors. This is partly due to the breathable design, which makes it harder to contain odors. But again, the biggest issue seems to be the mid/rear padding, which is highly susceptible to surface dampness and pressout that can result in odor formation. They aren’t the worst in this regard, but it’s an area that could use improvement as far as discretion scoring goes.
