Arena Powerskin ST NEXT Jammer Boy's Knee Length Swim Trunks

Built with recycled fabrics, it uses a fabric composition of 71% polyamide and 29% elastane, with 65% of the polyamide derived from recycled materials. The suit emphasizes reduced water absorption and drag, while offering greater compression and support for a streamlined, powerful swim.
