Heavy duty, Cordura, "Donut" style CCR wing is designed for diving with a CCR. The latest generation of our CCR wing brings with it redesigned ergonomics creating a lower profile wing that still provides 28lbs of lift. Added Cutouts in the center of the wing allow for superior hose routing, equating to a more streamlined and efficient diver. Cordura 2000 for maximum durability Inner bladder made of high frequency welded Cordura 560 with polyurethane seam coating
