Price and Final Thoughts

The PeekABU is a new diaper by ABUniverse (ABU) being released in March 2018 which they advertise as "the world's most absorbent diaper ever", promising 25% higher capacity than their previous premium line of LittlePawz/Space/Simple. This claim is bold: the difference in capacity between most high-end "premium" medical diapers and the previous wave of "super premium" ABDL diapers was itself around 25%. PeekABU purports to do this with a new SAP which allows the diaper to start thinner and expand more than previous products. PeekABU follows in the footsteps of the ABU PreSchool by having 4 different prints in the same bag, with differing full-panel landing zone prints on an otherwise all-white diaper. This diaper was originally slated for release several months prior, but citing production issues, ABU delayed it and simultaneously announced a companion all-white version called the Simple Ultra.I am reviewing the medium size as provided as a sample for review by ABUniverse in February 2018. The sizing information is not available as of this writing. Assuming that it matches the sizing for most other ABU diapers, this would mean that the small is listed as fitting waists of 22"-29", the medium is listed as fitting waists of 31"-36", the large is listed as fitting waists of 37"-44", and the extra-large is listed as fitting waists of 45"-52".The ABU PeekABU has printed packaging similar to other ABU products with a printed panel partially filling the front of on other otherwise transparent package. The panel has the 4 print characters peeking out from the 4 sides with the diaper logo in the center.It immediately stood out that the pack is noticeably more compact than that of ABU LittlePawz/Space/Simple, living up to the claim that PeekABU starts as a thinner diaper.The PeekABU is a white plastic diaper with four different full-panel landing zone prints, each depicting an animal character peeking out from the diaper, as drawn by babyfur artist Aito. The characters include a giraffe with blue spots, a raccoon, a blue husky, and a green animal with horns and blue hair that is not obvious but which was described in a Twitter poll as an orc. The characters each sit on a colored backdrop with a repeating motif of colored shapes including stars, circles, squares, and triangles. A contrasting color frames the outside outline of the landing zone print. The panels use bold and vibrant colors rather than pastel tones.Placed equidistant from the center of the landing zone are two blue stars. On the left, is one which encloses an "8" and on the right is one that encloses the ABU logo – meant to suggest that this is a print on a "size 8" baby diaper, which is a bit of an ABDL trope. What I didn't initially appreciate before putting the diaper on is that these are actually a functional part of the print in that they are consistent reference points for placing the lower tapes across all 4 prints.When first announced, the PeekABU print received some community skepticism for being too "furry". I not only wholeheartedly disagree, but I am going to lay down a marker and say that I think that, excluding replica prints,For roughly the past 20 years, nearly every baby diaper print from Pampers or Luvs, at least in the US market, has featured a head shot image of anthropromorphic animal or muppet character on the landing zone panel. Usually, these have been branded characters from popular television shows for preschool-aged children, and occasionally they have been unbranded animal characters such as the zoo animal theme seen on Pampers products around 2000. Typically, these prints have involved a character doing some type of aspirational "big kid" activity such as reading a book, but the concept of just having a character head peek over the edge was actually done on Pampers circa 2011. As baby diapers moved towards cloth-like covers and all-over prints, they had a design pairing characters on the landing zone with a coordinated print on the rest of the diaper. One counterargument to this defense of PeekABU's print that I've seen is that the specific anthropromorphic flavor of baby diaper character prints is somewhat specific to US versus non-US baby diaper prints – that the issue is the anthropromorphism, not the animal character across the landing zone – but I think this is an inherently bizarre argument to make about a print coming from a US ABDL company.I've honestly wondered why nobody had made a print like this sooner. I've assumed it was purely due to technical limitations, as I think the idea is intuitively obvious – thatthe most accurate baby diaper print an ABDL company could make would have the landing zone be one or a couple animal characters either just looking out from the panel or doing something. Notably, most of ABU's diaper stickers have followed from this concept; it just hadn't been done as the base print of an actual diaper before. The last gasp of all-white plastic-backed major-brand baby diapers had full-printed landing zones with head-shot images of anthropromorphic characters, with multiple different prints in the same bag. PeekABU is extremely believable as a design reminiscent of that era.To test their dry thickness, I stacked three diapers on top of each other, placed a heavy book on top of them, and measured their height. Together, the 3 diapers had a height of approximately 9.3 cm (3.7 in). Thus, the dry thickness of a single folded diaper is 3.1 cm (1.2 in).The ABU PeekABU uses a double-tape design with tapes that measure 4.1 cm (1.6 in) wide each. They are the same as the other clear tapes used on other ABU products.The outer plastic of the diaper has a soft, smooth, oily feel to it.The inside of the diaper is all-white and the padding is arranged in an hourglass shape. The padding feels soft, flat, and dense but not overly hard. There is a center area that feels less dense than the sides, arranged like a channel, and if you hold the diaper up to a light it shines through this center area more easily. The diaper has standing leak guards. It features elastic waistbands in both front and back.With the diaper outstretched, it measures 75.9 cm (29.9 in) in length, 63.9 cm (25.2 in) in width at the wings, 29.4 cm (11.6 in) in width at the center, and 22.0 cm (8.7 in) in width between the leak guards.To test the capacity of this diaper quantitatively, I performed two tests.First, I weighed a diaper and put it on. I then repeatedly dosed water into the front of it in 100 mL increments using a metered laboratory bottletop dispenser, followed by sitting down in a chair for 30 seconds each time to give the diaper a chance to absorb the liquid, then checking for leaks. When a leak occurred, I weighed the diaper again, and recorded the change in weight.Over 3 replicates of this H2O capacity test, the ABU PeekABU averaged 2584 mL with a standard deviation of 251 mL.During one trial of this test, I recorded qualitative information about the diaper as I added water to it. After 500 mL of water, the top part of the diaper under the landing zone was starting to feel very wet but the broader front of the diaper still felt dry. At 1000 mL the front was so widely expanded that I couldn't close my legs while sitting and it took effort to do so while standing. At 1300 mL the sides of my legs felt constantly wet. At 1500 mL I felt like I was sitting at the edge of a puddle. At 2000 mL I felt like I was half sitting in a puddle. At 2200 mL, I felt like I was fully sitting in a puddle. At 2500 mL, the diaper was sagging quite a bit as I stood. At 2600 mL, I felt like I was sitting in a pond. At 2700 mL, I felt liquid moving underneath me and the diaper leaked.I folded the diaper back up to compare its thickness to a dry diaper. It had expanded to roughly 12.7 cm (5.0 in), about 4.1x its original size, a notably extreme result.I then performed a second test in which I made normal saline (0.9% NaCl in H2O), weighed a diaper and put it on, then used a metered laboratory bottletop dispenser to dose 160 mL saline every 5 minutes until it leaked, sitting down between increments. I weighed the diaper afterwards and divided the resulting change in grams by 1.0046 to account for the density of saline to determine the change in milliliters. 160 mL is approximately equivalent to half of an average adult urine void, and this increment is loosely representative of a "half-flood".Over 3 replicates of this saline capacity test, the ABU PeekABU averaged 1506 mL with a standard deviation of 96 mL. Rounded to numbers of integer "half-flood" doses, the diaper averaged 9.3 "half-floods" with a standard deviation of 0.6 "half-floods".The tapes mostly held firm throughout these tests – actually so well that I have to give the unusual caveat that on one of my trials an upper tape actually ripped from the wing rather than slide on the panel on one of the last increments.The average dry mass of this diaper, based on 6 replicates across both tests, was 194.3 g with a standard deviation of 2.0 g.I weighed and put on a fresh diaper and wore it while going about ordinary activities. The diaper lasted a total of 7.5 hours before beginning to leak. During my test, I had about 6 wettings and 1 floods, recording a change in mass of 1285 g or roughly 8.0 "half-floods". This number is low relative to what might be expected from my testing, and I think more than other diapers it's meaningful here because anecdotally I can say that during the saline testing and when trying the diaper other times, it seemed clear that somewhere around 2/3 of the tested capacity, the diaper could be made to spot leak by sitting down too quickly or oddly before it had some time to absorb the liquid. I think my test result, while valid for my carefully-controlled test conditions, might overestimate real-world use a bit because this diaper seemed to have repeated issues wicking fast enough as it got towards its outer limits. All of that said, these test resultsare exceptionally high, and rank it on the same tier currently only occupied by Crinklz rather than the tier occupied by the previous round of high-end ABDL products such as ABU LittlePawz/Space/Simple and Tykables Overnights.With a 36" waist, I am at the top end of listed size range for the medium ABU products. I normally wear size medium in other diaper brands. This diaper seemed to fit my size well, and the thinner starting profile made it feel a bit roomier, at least at first. I wondered beforehand whether the tapes would be up to the task of a diaper that is intended to expand more substantially, but the tapes held great without little to no slippage at all.I received a pack of these diapers for the purposes of a review from https://abuniverse.com/ . Without shipping, both PeekABU and the all-white version, Simple Ultra, will be available at launch in single diaper samples for $6.00 (with a $5 discount for a future order for every two sample diapers ordered across brands), 10-diaper packs for $39.99, 40-diaper half-cases for $94.99, and 80-diaper cases at $179.99. ABU no longer includes shipping in its prices, and now adds $1 for samples, $5 for single packs, $8 for half-cases, and $12 for cases, bringing the final case price to $191.99.At the case size, this works out to $2.40/diaper and based on my test results this diaper holds 3.9 "half-floods" per dollar. This price means PeekABU is both meaningfully more expensive than most of the competition, but balanced against an exceptional capacity placing on a higher tier than nearly the whole market, it still delivers at this price as one of most efficient diapers in efficiency of capacity for price.Furthermore, PeekABU has, I strongly argue, the most realistic non-replica ABDL diaper print to date. This is a well-done print which really does feel authentic to me, paired with the further authenticity of multiple prints per pack. Compared to other top contenders, PeekABU has the most authentic print.Still, the high price and a lingering concern about absorption speed as the diaper nears capacity are keeping me from endorsing this as "the" rather than just "one of" the best diapers on the market. Right now it's a clear contender for that title, representing one set of trade-offs versus the other contenders. It's on the same capacity tier as Crinklz with a design that's actually believable but it costs fully 1/3 more than Crinklz and is therefore much less efficient. It has greater capacity than and I'd personally say more authentic print than Tykables Overnights, but the Overnights are roughly as efficient at their lower price and have superior tapes. The ABU BareBum at a far lower price point still clobbers all other ABU products in efficiency and strikes some middle ground in efficiency and realism between Crinklz and other contenders. Depending on what exactly an individual ABDL values most, there are strong arguments for "best overall" for PeekABU but not enough to deliver knockout blows versus the other top contenders; to my mind, this means we've entered into a really exciting time for ABDL diapers where the competition is fierce with the envelope being pushed on multiple fronts at the same time.As an overall diaper, PeekABU is extremely impressive. It excels in both capacity and realism; it has the complete package of appeals. There are going to be a lot of ABDLs who will try this and find it to be the best diaper they've ever worn, and very few who will be disappointed.
