### ⭐⭐⭐⭐⭐ Great tech suit!
*by R***5 on July 12, 2026*

Sizing was perfect, the suit fit perfectly, and my son dropped time due to the quality of the material. Tech suits are not meant to be comfortable, but this suit is durable and the fabric helped him get first place!

### ⭐⭐⭐⭐⭐ Perfect suit
*by T***R on July 29, 2026*

Good fit and made a difference for my 12U swimmer

### ⭐⭐ Poor quality
*by A***R on August 1, 2026*

Both pairs we bought were poor quality. Our first pair ripped down the back seam after first wear, so we had to buy a second pair, and with second pair - both labels/bar code peeled off before my son even raced. $220 down the drain! I will make sure I purchase directly from a swim store next time. Very disappointed!!
