Arena competition swim trunks for boys - ST 2.0 - Dark blue

The perfect—and by far our best-selling—first pair of competition swim trunks for new racers. 100% FINA approved, so they’re legal at both Danish and international swim meets.

Designed for racing, they’re made from a special water-repellent fabric that minimizes drag in the pool.

They provide solid muscle support without feeling overly tight, while still allowing complete freedom of movement.

Quick size guide by height:

- Size 6-7 years = 116 cm tall
- Size 8-9 years = 128 cm tall
- Size 10-11 years = 140 cm tall
- Size 12-13 years = 152 cm tall

With these trunks on, your boy will feel like he’s flying through the water compared with his regular swimwear—and he’ll probably set a few new personal bests.

Combine that with the sleek black design, and he’ll look razor-sharp on the starting block at the next meet.
