Review: High Quality and Cute - Super cute design, Great quality of material, and has held up well with multiple washings. The color does not fade in the chlorine. The fit is both comfortable and functional. Great swimsuit!
Review: Loved. - Got this instead of disposable swim diaper because the minimum weight did not fit my 3 month old. These worked very well & baby did not seem uncomfortable. Slightly tricky to get on, but was as expected since they need to be tight to work. I have not washed it in a machine yet, but has held up through a sink wash so far.

### ⭐⭐⭐⭐⭐ Love it!
*by S***R on June 12, 2025*

Love it use it for swim classes! Great price great quality. There is definitely a method to put this diaper on. It is designed tight around the thigh area so that the diaper contains accidents the baby has. Baby might need some getting used to but it’s awesome and we have been using them for a little over 1.5 years.
