Arena - Women's Powerskin Carbon-AIR² Open Back - Black/Black/Gold

Race with freedom, support, and streamlined confidence in the Arena Women’s Powerskin Carbon-AIR² Open Back Kneeskin. Designed for competitive swimmers, this lightweight women’s tech suit combines flexible movement with race-focused compression, making it ideal for swimmers who want a fast feel without unnecessary restriction.

The outer shell is made from a single piece of fabric, helping to reduce stitching and create a smooth, drag-resistant surface through the water. Inside, the 3-piece lining design allows the body to stretch more naturally, giving swimmers a greater range of motion during starts, turns, and every stroke cycle.

Integrated horizontal carbon fibre bands help lock down on the muscles for enhanced support and control, so swimmers can feel stable, powerful and connected in the water. The open-back design adds freedom through the shoulders and back, while the lightweight construction supports long-lasting comfort during race-day wear.

Fully World Aquatics approved, the Powerskin Carbon-AIR² is built for swimmers competing in galas, club meets and championship events who want a technical kneeskin from one of swimming’s most trusted performance brands.
