Arena Powerskin Primo CB 1-Piece


2024 Fireflow Collection – Flow like water. Fueled by fire.

Developed with elite swimmers, FIREFLOW is inspired by the winning balance that empowers athletes towards excellence: the passionate drive and focused control, the burning heat of fire and smooth flow of water.

A new era in race suits is here. The POWERSKIN Primo eliminates compromise, delivering powerful compression and extraordinary flexibility in one physics-defying suit. It goes on in less than 5 minutes while still delivering our highest level of compression. It’s the pinnacle of speed and comfort in a technical race suit.


  • Our most powerful compression combined with extraordinary elasticity thanks to Hyperforce, the first ever tensoelastic fabric.
  • Speed in AND out of the water. Finally a high-compression suit that goes on in under 5 minutes to streamline your race day routine.
  • Permanently hydrophobic TPU coated fiber provides for maximum water repellency over the life of the suit.
  • Hyperforce fabric utilizes a unique flow-channeling surface to improve hydrodynamics and minimize surface drag for maximum speed and streamline performance.
  • A completely new internal taping construction provides powerful support that lifts the legs and hips for optimal body positioning.
  • Available in long-torso sizes for a near-custom fit and supreme comfort without sacrificing compression.
  • Redesigned shoulder strap construction provides more stability and fewer pressure points for optimal comfort and range of motion.
  • World Aquatics (formerly known as FINA) approved.
