Best Swim Diapers for Baby Girls of 2025

"I love this reusable swim diaper! It fits my daughter perfectly and has held up well during our beach trips. We didn't have any leaks at all during our 6+ hours of fun. Just a heads up, it does run a bit small, so I definitely recommend sizing up, especially for kids with thicker thighs."

"I bought this swim diaper along with a rashguard and hat for my little one, and she looks adorable! It's so easy to use; I just toss it in the wash, and it comes out clean. I prefer this to regular water diapers because it's less wasteful."

"We used this for swim lessons and had no issues at all! We liked it so much that we ended up purchasing two more in different colors."

"I find this product very useful for the pool and beach, but it comes smaller than expected."

"I decided to size up to 24 months for my 12-month-old, and it fits perfectly. However, after washing, one pair trapped air, which affected my daughter's swimming."

"I love this product because it fits my toddler perfectly, offers sun protection, and is super cute!"

"I found these swim diapers to be super cute and much more comfortable for my little one. She's 20 months old and does swim lessons requiring a disposable swim diaper underneath. These fit her snugly around the thighs and waist, and they glide right on, making them easier to use than the snap ones we had before."

"Originally, I purchased a size for my soon-to-be 5-year-old, but they were too big. After returning them and getting a size down, they fit him perfectly. He loves the shark designs and hasn't complained at all since we switched!"

"I bought these for my grandson to avoid continuously purchasing disposable ones. They are a little big on him since he's only 17 pounds, but they work perfectly for the kiddie pool. He moves around comfortably and doesn't whine about wearing them at all!"

"I've bought these swim diapers multiple times for my kids, and I absolutely love them! They hold everything in and give me peace of mind while they swim. The material is great, and I appreciate the variety of colors. Just a heads up, they do tend to run small, so consider sizing up!"

"This is definitely my go-to swim diaper! I've purchased it in several sizes, and it fits well and does the job perfectly. We haven't experienced any leaks or accidents, so I highly recommend it!"

"I chose this swim diaper for its reusability and was not disappointed. The quality is impressive, and it fits true to size. So far, we've had no leaks or issues, which makes it a fantastic choice for us!"

“I absolutely love the quality and feel of these swim diapers. Even though my little one wasn't keen on wearing them, he confidently said he’s a big boy who can control his bowels—OMG!”

“I can't believe how much I've used these! They're the softest material ever and after several washes, they still look brand new. They fit perfectly and don’t fall down when wet, plus the snaps on the side are a lifesaver for potty training. I highly recommend them!”

“I prefer these over disposables. They aren’t too thick, making them easy to put on and take off. Plus, they’re super soft. They worked perfectly for my family!”

"I found these reusable swim diapers to be amazing! I purchased them for my baby to wear under her swimsuit. Although she is only 3 months old and has a tiny waist, they fit perfectly on the smallest snaps. The colors are vibrant, and the material quality is impressive. They don't feel bulky but seem thick enough for containment. Plus, I love the wet bag that comes with it!"

"I bought these for my second child during our vacation, as disposable swim diapers didn't work well for her loose stool. I was pleasantly surprised at how well they contained everything, and they seemed comfortable and stylish. The cleaning process was not my favorite, but it was manageable, and they looked stunning!"

"These swim diapers are great! They are easy to put on and take off, and my baby seems comfortable in them. We had one bathroom incident in the pool, and I didn’t even notice it, which shows they work effectively! My only concern is that my baby is quite large, and I’m unsure how much longer he will fit into them."

“I absolutely love these swim diapers! They are adjustable, washable, and fit my baby perfectly, providing a secure and comfortable fit during swim time. The flower designs are just adorable, and the quality is fantastic. Plus, being reusable, they are eco-friendly and cost-effective. I highly recommend them to any parent seeking a reliable and cute option for their little one!”

“I was thrilled to find swimwear for my 1-month-old who is 10 pounds. These diapers fit him perfectly and are comfortable. The adjustments will allow them to grow with him. They have a mesh inset that stops solids but won't prevent liquids, which is something to keep in mind. Overall, they work wonderfully for us, and I adore the cute designs!”

“We took our freshly 1-year-old to a water park and these diapers were amazing. We had one poopy accident while in the water, and this diaper contained everything so well that my husband had no clue until we took a break. They were easy to clean in our hotel room, fit securely, and I love that they grow with my child. We’re looking forward to more water adventures with these!”

"I love that these swim diapers are adjustable. My daughter has been using them since she was six months old, and even at 16 months, they still fit her well, providing plenty of room for growth. They hold everything well and are machine washable too!"

"These swim diapers are comfortable and adjustable. I used to hate disposable swimmers because they would fill up quickly and make my little guy waddle. With these, he can play freely without any issues!"

"I love these swim diapers! They're really absorbent without being overly so. Super easy to clean—I just toss them in the wash and hang them to dry."
