Race with confidence in the Women’s Open-Back Powerskin Primo Kneeskin Limited Edition – Emerald Green Boa.
Created for elite swimmers who demand the highest level of performance, this competition suit combines advanced compression, exceptional flexibility, and cutting-edge hydrodynamics. Whether you’re targeting a personal best, a podium finish, or a championship qualification, it helps you maximise every stroke from the start to the finish wall.
The Powerskin Primo is the world’s first tensoelastic racing suit. This breakthrough design combines powerful compression with remarkable elasticity, delivering support without limiting movement. As a result, you can maintain a strong, streamlined position while still enjoying the freedom needed for explosive starts, efficient turns, and powerful underwater phases.
Made with innovative arena Hyperforce™ fabric, the suit adapts naturally to your body while maintaining race-ready compression. Unlike traditional race suits that can feel restrictive, Hyperforce™ allows greater flexibility and comfort without sacrificing performance.
In addition, the permanently hydrophobic TPU-coated fibres repel water effectively, helping reduce water absorption and drag throughout your race.
The advanced internal taping system provides targeted muscle support and helps lift the hips and legs into a more efficient swimming position. This improved body alignment can help reduce resistance in the water and support better energy transfer through every stroke.
Race-day preparation is also easier. Thanks to the extraordinary elasticity of the fabric, the suit can be put on in under five minutes, saving valuable time and reducing pre-race stress. Furthermore, long torso sizing options provide a near-custom fit for swimmers who need additional upper-body length while maintaining the suit’s compression benefits.
