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.
Hyperforce fabric’s incredible elasticity allows for custom waist height adjustment from low to high.
