This is the newest generation of our successful NRS Extreme and, ounce for ounce, the industry's best drysuit. It utilizes TriTon 420-denier tricot fabric, making it rugged, waterproof, and highly breathable. Heavy-duty YKK waterproof zipper across the body, plus extra-tough latex gaskets, reinforced Cordura seat, elbows, and knees. Neoprene outer cuffs with hook-and-loop closures on neck, wrist, and ankles help keep you warm and protect gaskets from tough use. Reflective arm stripes and shock-cord waist adjustment. Whether you kayak, raft, tour, or canoe, the Extreme will exceed all your expectations. Fabric: 420-denier Triton™ with tricot lining. Extreme Relief Drysuit has all the same features as the Extreme, plus the necessary extras-a relief zipper and the full coverage of latex socks. XXL
