Engineered for competition, the Fusion 2™ Brief Swimsuit uses some of the most advanced aquatic engineering to ever enter a pool. Showcasing hydrophobic construction and low-profile flatlock stitching, the RFUSN6A Brief reduces drag for maximized performance in the water. Combined with tried-and-true innovations like Fabrication Logic and Fluid Channel Dynamics, Fusion 2™ speed suits allow for superior flow, while calenderized Isolated Compression technology provides more glide efficiency and increased speed. It’s what happens when the past and the future meet at the swim lab.
