Every aspect of this suit is designed for high performance without sacrificing comfort. Since it's introduction in 2006 the Reaction has helped more athletes accomplish their goals than any other wetsuit. Premium 39 cell Yamamoto rubber achieves superior buoyancy throughout the entire suit. Proven RST panels improve stretch throughout the chest and back, while the finest Japanese sourced neoprene delivers enhanced buoyancy. Slippery SCS coating reduces drag. A low neckline and VO2 chest panel create a suit that optimizes energy and swims as fast as it looks.
