"We love how adjustable these are and the mesh lining. It’s also a bonus that Thirsties has the cutest prints!"
"Perfect swim diapers, they have been holding up very well. Very cute prints and the quality of the diapers and mesh is really good. Will definitely be buying more of these!"
"These are my favorite because of the interior and because of how they snap. There is another brand I love also that is comparable with fit but are a little more expensive than these!"
"We are in the water a lot during the Summer and so this was a must! I haven't experienced any leaking yet, and the sizing is accurate and convenient! I bought a size 2 for my 20 lb little guy."
"The prints are great and these are not bulky either. The snaps allow them to fit longwe and easier to change in my opinion."
"We loved it so much we bought it again when it was time to size up! Perfect for our swim classes."
"This is a must have for frequent swimmers! We have already kicked off summer by going to the pool almost daily, and this diaper is holding up super well for the amount of use. Will definitely be buying another one soon."
"Love the pattern, the colors are just as expected. Thirsties swim diapers are our favorite!"
"We don't cloth diaper but I was tired of the disposable swim diapers. So glad we gave this swim diaper a try! I love that it's adjustable and he'll be able to wear it for quite a while! The print is so incredibly cute too!"
