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.

Is this suit a good fit for my body shape?

How do I care for my tech suit? 

Chlorine is the enemy. Flushing out the chlorine as soon as possible after you race by lightly squeezing under cold water for around 60 seconds. Dry laying flat without heat from radiators or hair dryers. Do not use detergent or put in the washing machine - a droplet or 2 of liquid soap every once in a while with you cold water rinse is enough. 

What size do I need?

Sizing is extremely difficult. It is no good investing in an expensive tech suit that does not fit you properly! The size guides are the best resource here. If you are between sizes go by the Hip measurement. Talk to friends or talk to us for advice.
