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 neprene means better performance and fit, keeping you comfortable in the water for longer periods of time. Key features for the Cyclone tops include: 100% 4-way Stretch Quantum Foam construction. Durable flat lock seam construction. 1yr warranty.
