Approved By FINA High compression core - pressure where you need it. Water escape portals - strategic draining to keep water from pooling in the suit. Silicone leg grippers - comfort without compromising hydrodynamics. Ultrasonically welded seams - no stitching to slow you down. Hydraphobic materials - our lighter fabric blend decreases absorption and thus minimizes drag even more. Laser cut fabric - each suit is precision cut for performance. Unibody Design - fewer seams which means fewer points of failure and less drag.Rocket Science Sports
