The Classic XT Wing (model BC 5400) is the workhorse of our series of wings. With a history dating back to our early days, the Classic Wing has been dived and proven many times over, leading the way for divers to penetrate deep into caves, explore shipwrecks, or cruise comfortably deep on an ocean ledge. Designed solely for double tanks and with the option of a single or dual bladder, the Classic XT  provides 65 lbs. (27.2 kg) of lift, which can accommodate two 104 ft3 (17 L) back mounted cylinders and two 80 ft3 (11L) stage bottles.
