To get away from the crowds and truly test your limits, suit up into Roxy's 5/4/3 Performance Chest Zip HYD HD Wetsuit and brace yourself for the frigid waters that go along with empty beaches. To keep your mind off the temperature and your muscles warm, Roxy built this ultra-warm wetsuit with all of their top technologies. Lightweight limestone-based F'N Lite neoprene and a stretchy Thermal Smoothie at the chest and back work to insulate heat and repel wind and water while feeling like second skin. And for extra warmth, Roxy reinforced this suit with Far Infrared WarmFlight thermal lining technology--mineral enriched fibers that work to transform body heat into infrared energy to generate warmth and increase blood flow and oxygen supply so your muscles remain active in cold temperatures. Triple glued and blind-stitched seam construction is reinforced with Hydrolock and Red Seal seam sealant to ensure a leak-proof design without compromising flexibility. For a comfortable and ergonomic fit, this suits cuffs and ankles are finished with fused edging, while the Flush Lock 2. 0 elastic banding works to prevent flushing. And for safety in dark and rugged conditions, this suit is equipped with Ecto-Flex knee pads to give you durable protection against your board and rocky shores while remaining lightweight and flexible.
