Completely redesigned, the new Hyperflex Cyclone-2 blows away all competition at this price point! We were shocked and totally stoked about how high-end these suits feel for such reasonable prices. The entire Cyclone-2 line is made of Hyperflex"s new Quantum Foam neoprene; a neoprene distinguished by its buttery soft feel and incredible stretch. This superior neoprene means better performance and fit, keeping you comfortable in the water for longer periods of time.

WEB (Water Entry Barrier) behind zipper prevents cold water entering through the zipper. Mesh skin chest and back panels for grip and wind resistance. - Duratex knee pads.
