Review: Follow the size chart given for youth jammers - My son loves the fit of the jammers. He loves the leg compression as well. I measured his waist and hips and followed the size chart. DO NOT SIZE DOWN when buying these youth jammers. Stick with the size chart given. My son waist is 24 inches and hip 27.8 inches and his height is about 148cm and i bought the size 26 jammers.
Review: Good Jammers- hand wash - Very good jammers for 12U competition. I read a review stating the 12U compliant check box was coming off and they thought these were counterfeit. Not true. You do need to hand wash them though. Don’t run them through the machine with the rest of your clothes.

### ⭐⭐⭐⭐⭐ Arena techsuit, suits for competition
*by C***S on February 13, 2026*

Definitely worth buying this techsuit for my 8 year old son. Who got first ppace in the 50m boy backstroke and breaststyle. It definitely made his swimming compete as the suit is meant for it. I am ordering one more time in different color as a reward for his achievement. If you are looking for a swimsuit for competition., don't hesitate to buy a proper swimming competition like tech suit as it will help them win the competition.
