### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    great product and quality
  

*by B***Y on Reviewed in the United States on April 24, 2019*

I really like this suit, it looks like it is designed to last with chlorine. The cut is great and quality seems good too. However the size chart did throw me. I usually order a size 21 in speedo or TYR for my 9 year old boy who wears a size 8 but the size chart suggested to order a size 25 (for a size 8). So I decided to order the 23 and it ended up being too big. Just measure the waist and don't try to guess.

    Great for under swim trunks
  

*by N***S on Reviewed in the United States on May 9, 2019*

We got this for our son to wear under his swim trunks since we don’t like just the mesh lining in his suits. We normally have him wear regular undies but got these so they’d do better drying after swimming and last longer. He said they were comfy and they hang-dried quickly after swimming. I suppose you could wear them on their own....they looked like little boxer briefs on him! Haha.

    Perfect. Not a Speedo, but not bulky
  

*by E***D on Reviewed in the United States on June 24, 2020*

Americans dislike the dreaded "Speedo", which is really just elastic swim shorts that resemble briefs instead of boxershorts. But the typical long swim shorts are a pain for kids to deal with. They cling to your legs, are hard to take off when wet (unless you do it under water, which only works with privacy), and are hard to tie.These are the elastic material, easy to put on and take off at any age, they provide a hint more coverage than the brief style (think boxer briefs), stay up without tying the ties so tight they can barely breathe. They love them.
