The Boys Crowded Swim Jammer by Arena is designed for young swimmers who want reliable performance, comfort and durability in every session. Its chlorine-resistant, quick-drying fabric helps retain its shape during intensive training, while the streamlined fit and compression support an efficient body position and reduced drag in the water. Finished with a comfortable front lining and adjustable internal drawcord, these swim jammers stay securely in place without restricting movement.
