I have had steady urinary and occasional bowel incontinence for over 20 years as a result of nerve damage from a motorcycle accident and over these decades I have worn too many brands and styles to recall. I have worn Tranquility brand plastic-backed diapers, including their Slimline diapers and their All-Through-The-Night (ATN) diapers. Comparing these two styles to each other, the Slimlines are thinner, with less absorbent core filler material than the ATN's. I have used the Slimlines while out and about, but I needed booster pads inside to better prevent embarrassing leakage. To not use boosters was always a recipe for disaster, unless I was making a short trip to the grocery store or to pickup a food order because they would inevitably leak. For clarification, my bladder leaks urine pretty constantly in small dribbles, nonstop, without my knowledge whatsoever throughout day or night. I just don't feel anything happening down there and don't realize when my diaper is needing to be changed until there is leakage or the diaper swells enough to be noticeable when I walk or visible under my clothing. A Slimline just doesn't last me for more than two or three hours, especially when I have had a lot of water or some other drinks, or when I have experienced bowel incontinence. In comparison, the ATN diapers get me through twice as many hours and very often can allow me to survive most of my workday without a diaper change until the last hour or so of my workday, except when I have a bowel movement which requires an immediate trip to the restroom, of course. Overnight, the ATN's work pretty well, but I have noticed some leakage from the top-backside of the diaper, which may have more to do with there being no elastic in the tops of the diapers and the fact that I change positions in bed from lying on my back to lying on my side, back and forth. Both the Slimlines and the ATN's are discreet and not thick, which some wearers appreciate. As for me, I have worn slimmer diapers, as well as thicker and bulkier diapers, and I really don't care which style of diaper I wear so long as it does its job to keep me and my clothing dry. I have tried the cloth-like diapers and, in my experience, they tend to leak both urine and odor, which is why I have long preferred plastic-backed diapers. Yes, plastic-backed diapers can be somewhat noisy, making a "crinkling" sound when I walk, sit/stand or move, but either nobody else hears it because my clothing muffles those sounds or other people respect my privacy and say nothing (or don't realize the sounds are coming from my diaper). Either way, the crinkling is not a problem for me. I much prefer the noises (loud or soft) to leakage from my diaper. The Slimlines and ATN's are both plastic-backed styles. These both have elastic inner leg gathers, too, which greatly helps to contain and channel voids (urine and feces), which is a feature that some cheaper diapers do not incorporate into their designs in order to reduce manufacturing costs, in my opinion. Even the ATN's with its increased absorption capacity and fast wicking due to its unique peach-colored core down the inside middle of the diapers does not compare with the high-end designer diapers such as those targeted to the ABDL (Adult Baby and/or Diaper Lover) markets, but the cost of the Tranquility ATN's, even with the addition of Tranquility's diaper boosters/inserts to increase void capacity, is significantly more affordable, especially when purchased in bulk (Tranquility's Slimline and ATN medium diapers come in case sizes of 96) and on a recurring autoship monthly basis, which offers a further discount, as well as relieving my worries about running out before remembering to order more diapers and needing to rush ship an order. I normally go through about three, sometimes fpur, diapers per day (morning, evening and overnight), but I can burn through diapers during the Summer when I drink more fluid due to the heat. I also change more frequently when I sweat more, which a plastic-backed diaper can cause you to do, or when I can smell my diaper's contents when I sit or walk, which makes me self-conscious that others, too, can "smell me"...or when I just feel "icky" or notice my diaper bulging through my clothing, or my diaper causing me to walk differently, or when I can hear squishy noises or feel clumping in my diaper (neither, of which, is usually an issue with the ATN diapers, but is often a problem with those cheap diapers that my insurance and the hospital provides for me). So, yeah, I would recommend the Tranquility ATN's for most folks who need them, like myself. They are not fancy with designs all over them, or made to last all day long, but for those qualities I would recommend diapers made for ABDL customers.
