Feel the race-day energy the moment you step onto the blocks in the arena Womens Powerskin Primo Open Back Kneesuit. arena engineered this cutting-edge racing suit for swimmers who demand maximum speed, power and freedom of movement. Most importantly, it introduces arena’s revolutionary tensoelastic technology. This innovation delivers the brand’s highest level of compression while maintaining exceptional elasticity, so you move freely and efficiently through every stroke.

The Powerskin Primo simplifies your race-day routine. You can put the suit on in under five minutes, even with its high-compression design. As a result, you spend less time preparing and more time focusing on your performance. In addition, World Aquatics approval means you can race with confidence at the highest levels of competition.

arena constructs the suit using advanced Hyperforce™ tensoelastic fabric. This technical material compresses key muscle groups to support powerful movement while still allowing natural flexibility in the water. At the same time, permanently hydrophobic TPU-coated fibres actively repel water. Consequently, the suit reduces drag and improves hydrodynamics, helping you maintain speed and efficiency throughout your race.

The Primo also improves body positioning in the water. arena integrates new internal taping that lifts and stabilises the legs and hips. This targeted support helps swimmers maintain an optimal racing position, which promotes stronger propulsion and better overall balance during competition.

arena also focuses on comfort and fit. The Powerskin Primo comes in long-torso sizes to suit swimmers who need extra upper-body length. This design creates a more tailored fit across the shoulders and torso while preserving the powerful compression required for elite racing.

If you want a racing suit that combines advanced compression, flexibility and hydrodynamic performance, the arena Womens Powerskin Primo Open Back Kneesuit helps you push for faster times when it matters most.
