W Powerskin Primo Closed Back - closed-back women's competition swimsuit
Primo is the world's first tensoelastic competition swimsuit. Primo combines effective compression with exceptionally good stretch in a completely new way. The suit supports the muscles while allowing plenty of freedom of movement. This versatile new suit is suitable for all swimming styles and distances.
The suit is the result of several years of development and research by Arena, carried out in close cooperation with elite swimmers. It cannot be compared to earlier race suits, as it is based on an entirely new technology rooted in textile innovation. The word Primo means "first" in Italian.
The suit's new Hyperforce™ fabric is tensoelastic (tension + elasticity); the fabric is firm yet flexible. Primo brings together the highest compression, durability and a completely new kind of stretch throughout. The suit feels pleasant to wear and does not restrict movement.
The Hyperforce™ fabric has a flow-guiding surface that reduces water resistance and improves glide. The fabric is naturally water-repellent TPU fibre, which further improves hydrodynamics. Thanks to the material, the suit can be recycled at the end of its service life.
The front of the suit features the X-tape structure familiar from Arena's Carbon Glide suit, placed inside the suit. The X-shaped taping supports and stabilises the core and connects the upper body to the hips. The taping helps you notice if your body rotates too far during a stroke and brings you back into an economical, streamlined swimming position.
The back of the suit has strong taping running over the buttocks and rear thighs inside the suit. This taping lifts the hips and legs, makes leg extension easier and helps maintain the correct swimming position when tired. The lift from the taping is especially noticeable during turns and the dolphin kick.
The flexible suit is easy to put on, which significantly speeds up race-day routines. Primo can be put on in five minutes, whereas a traditional competition swimsuit could take 30-45 minutes to put on. Even so, choose the same size as your previous Arena competition suit or follow the size chart. How quickly the suit goes on does not indicate whether the size is right. The flexible Primo is comfortable to wear and still delivers top-class compression.
For the first time, an Arena competition suit is available in two different lengths, according to upper-body length. The longer length is available in sizes 30-34. Added fabric on the straps increases comfort, and a silicone band at the leg opening keeps the leg in place.
