Check the listing for details. Hollis DT 50 Wing BCD - Technical Accessories (208.1254.052). Condition: New. Listed at 439.95 USD. The DT 50 Wing features a 360 degree tapered profile for heavier cylinders, to increase lift towards the hips, promoting better horizontal trim in dive position while still allowing perfect surface floatation. The DT 50 is focused on the dedicated drysuit diver, with heavier cylinders in cold water. Tank slots included on both models, which allows the occasional single tank dive without the need for a single tank adapter plate. This reduces weight and unnecessary accessories while traveling. The bladder is a two-piece design, with a rugged 1680 Cordura nylon outer shell to prevent abrasion and punctures, and a 420-denier nylon inner bladder to maintain buoyancy. The lower OPV is easy to reach for venting gas while horizontal or heads down, and the inflator design is a K style with a rugged crushproof rubber hose for easy positioning and oral inflation should you need to.
