Designed for cold-water divers who wanted a wing with enough lift to wear heavyweight single tanks or medium-weight double tanks. In order to achieve this versatility, the Rec Wing employs a Gusset Control System (GCS) cord woven through tabs on the front face of the wing. When tightened, the cord limits lift capacity so the Rec Wing can be used with single backmount tanks. This also helps to prevent the wing from wrapping around the sides of single backmount tanks in a "taco-shaped" effect, which creates drag and instability.
