Newbie Guide

Outer layer is a nylon polyester blend and the inner layer is a dark mesh lining. The ingenious dark lining will hide any unfortunate stains. Like all swim diapers, these are designed to allow liquids to pass through, but contain solids.

No, you do not! Swim diapers are not designed to catch pee, just any poop your little may have in the pool.

The swim diapers can be washed alongside your cloth diapers using your regular wash routine. Don’t cloth diaper? You can wash these with your regular laundry just make sure to avoid the use of hot water (warmer than 140F/60c).

These swim diapers dry fast, we recommend hanging to dry to prolong their life.

In short, no. Quality swim diapers with honest marketing cannot contain pee in the pool. Our swim diapers are designed for a snug fit that ensures that you, your baby, and your unicorn shaped floaty are the only ones bobbing around in the pool. While the diaper is stellar at keeping poop contained, water and pee are able to pass through. This is so that tiny tush isn’t full of water - a waterproof material would still allow water through when submerged for swimming, and then contain water inside of it when your little one get’s out of the pool. (there’s nothing worse than a saggy water butt and a cranky/uncomfortable baby at the pool, amiright?)

Swim diaper

My daughter loves this swim diaper. Her son who is only five months old already loves the water. The adjustable swim diaper will be used for many more months..

Hey Rebecca! Thank you so very much for taking the time to review your Reusable Swim Diaper! We think it is 'swim-ply' wonderful that your daughter and her son are loving the swim diaper. The adjustable sizing is great for even years if necessary! It can fit kiddos from 10-45 lbs! We hope that you have a splashy day! - Amanda @ Lil Helper

Absolutely comfortable, cute and a great value!

I'm a first time mom of an almost 5 month old girl (time flies!) and we had an upcoming trip to a lake. So, rather than the disposable swim diapers, I knew that I wanted one of Uncle Mo's swim diapers going in. I initially got sucked in by the wonderful advertising videos and bought myself some lifesaver mats for my baby prior to her arrival and really really love them!

But anyway, I knew going in that i wanted these. They will last a long time; they're breathable and well made, with lots of snaps for different sizing, They fit seamlessly under my daughter's swimsuit (but will also be excellent without!) They allow liquid to pass through as they're supposed to, and don't hold the wetness. Did I mention how cute they are?? I bought 2 in a bundle deal so that we have options for multiple water experiences. Thoroughly looking forward to my next use of the swim diaper. ❤️

Hi Christy!! Thank you so very much for taking the time to review your Adjustable Swim Diaper. It is 'swim-ply' the best reading how much you and your daughter are enjoying the breathability, flexible sizing, and cute design. We hope that time goes very slow this summer for you and you can soak up all of the best memories together, lake side and beyond. Thank you for choosing Lil Helper! - Amanda @ Lil Helper

Loved it!

Comfy swim diaper! No plastic crinkly diapers anymore. We used it at the water park, it was great and fit under his swimsuit

Hi Kate!
Is there anything worse than the crinkle of disposables? I think not!
Our SwimSavers are designed to be especially comfy for little ones in and out of the water so they can play all day! Glad you got such great use out of yours and thank you for the wonderful review and sweet pics!
Happy splashing!
