Great!
I’m so glad I found this reusable swim diaper! It’s incredibly well-made and fits my toddler perfectly. The material is soft yet durable, and it does an excellent job of preventing leaks, giving me peace of mind during swim lessons. The adjustable fit ensures comfort as my little one grows, and it’s so easy to wash and reuse. What’s even better is that this is the only brand allowed at my toddler’s swim facility, so I can rest assured that it meets their strict guidelines. It’s been a great investment and a must-have for anyone looking for a reliable, eco-friendly option for swim time. Highly recommend!

Perfect little thick speedo for babies and toddlers. Just be careful of the sizing!
Love this little Speedo diaper for my 3yr old. And 4t was perfect for him with give to 5t! They have sizes that are weird so if you have a baby small and medium are perfect! Like size 2 diaper to 3. Toddlers from 18mths to 24 would be large-xl depending on thickness of the legs. These have awesome stretch on the legs and waist! And fit great over a regular diaper as well.

Great diaper, we used them for years
We bought these for our autistic son, just in case of an accident. They worked great, kept in what needed to be kept in and let liquids out. They aren't designed thick and bulky like a normal swim diaper, which is nice for an older child wearing a swim diaper. Just throw away the solids and wash it. They have never stained and they kept their color. We probably used them for 3-4 years and they are still in great shape.

Nice suit, runs very small compared to Tuga or Sun Busters brands. I got a 4T for my son who just turn 2 and weighs 36 lbs and is 38 inches all. He has chubby legs and the elastic fit fine and did not cut off his circulation or leave any marks.

Good for extra protection
These are quite snug, but that's probably a good thing. My four-month old, average sized daughter, is currently wearing the 6-12 month size. For reference she's 13lbs and 24". My two-year-old son (who is small for his age) is currently wearing the 12-18 month size. He's 34" and 24lbs. We bought these to use over regular huggies swim diapers for additional protection and prevention of leaks in the pool during swim lessons. We've also had my son wear one by itself under his swim trunks. They seem comfortable and really look like a speedo when worn alone. As I mentioned before, they do fit snuggly and I think that's so that they'll hold in those number twos. The material is kind of thin and not as plastic-ky as the pampers or huggies swim diapers. If worn alone, I don't believe they would hold liquidy number twos, as in, those of a younger, formula or breastfed baby. Even though the directions on the tag say to hand-wash, I have accidentally washed and dried one and it just so happened to come out perfectly. No shrinkage or shape changes. Do you NEED one. Probably not. But if you want something that's perhaps more comfortable than the pampers or huggies, or you're looking to prevent any brown leaks in the pool, then I would suggest them. Overall, I was pleased with the quality and purpose of the purchase.

They run VERY small.
These definitely run VERY small! My son is 18 months and based off the weight they mention he should be in a XL. I ordered a 3T after reading the reviews on here and I am so happy I did. They fit perfect with a little room to grow. The material is nice and they aren’t to bulky so they fit perfect under his trunks. Not sure if they hold pee or poop yet but the disposable didn’t do much of a good job with pee when we would get those anyways.

Saved us from catastrophe
It works! The worst happened at a public pool but we were able rush to the edge of the pool, climb out, and make it to the locker rooms without a hint of anything escaping. I was afraid it would be done for after such rough use (it was very full), but it was easy to clean up good as new. It’s probably not quite as effective as our other pair, a different design that’s tighter and longer, but it works well enough and is gets fewer complaints about comfort.

Cute but small
We ordered this swim diaper for my daughter based on the size clothing she wears. These are intended to fit snuggly. and the first order was too small and we had to return for a bigger size. We have worn these 2x/week for 3 months during swim lessons and the diaper has held up nicely. We have also machine washed these 2x/week without any issues.
