The arena Powerskin Primo Closed Back is a women's closed-back racing swimsuit from the Neon Blaze special collection.
Primo is the world's first tensoelastic racing swimsuit. It combines effective compression with exceptional stretch in a new way. The suit supports the muscles while allowing plenty of freedom of movement. This versatile new suit is suited to all swimming strokes 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 previous race suits, as it is based on an entirely new technology built on textile innovation. The word "Primo" means "first" in Italian.
The suit's new Hyperforce™ fabric is tensoelastic (tension + elasticity): 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. It helps you notice if your body rotates too far during the stroke and guides you back into an economical, streamlined swimming position.
At the back, firm taping runs over the buttocks and rear thighs inside the suit. This taping lifts the hips and legs, eases leg extension and helps maintain the correct swimming position when tired. The lift is especially noticeable in turns and dolphin kicks.
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 racing suit could take 30-45 minutes. Even so, choose the same size as your previous arena racing 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 while still delivering top-class compression.
For the first time, an arena racing suit is available in two different lengths, according to torso 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.
