Additional Info
StretchFlight & WarmFlight®
Extra warm 3d lining, full taping for watertight seams, external seal for added warmth, flexible and durable body-mapped neoprene. The WarmFlight Eco Infrared is the warmest thermo liner built with infrared technology that traps and reuses body heat from with the raised fabric surface, and keeps you surfing longer in colder water. Flexibility where you need it. durability where it counts. This neoprene is designed to give you the best of both worlds. A strechy liquid seal over the GBS seams prevents leaking without hindering flexibility. Quiksilver is more committed than ever to ensuring their wetsuits perform in the water but have low impact on the environment. Quiksilver wetsuits feature sustainable materials and processes. These suits are made better by using natural limestone neoprene to replace petrochemicals, water-based lamination and glues to eliminate the need for toxic solvents, and reycling scrap rubber tires and neoprene waste.
