The Hollis DT50 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 floation. The DT50 is focused on the dedicated drysuit diver.

Both models include integrated tank slots, allowing for occasional single-tank dives without the need for a single tank adapter. This design reduces overall weight and eliminates unnecessary accessories, making travel simpler and more efficient.

The bladder features a durable two-piece construction, with a rugged 1680D Cordura nylon outer shell for abrasion and puncture resistance, paired with a 420-denier nylon inner bladder to maintain reliable buoyancy. A conveniently positioned lower OPV allows for easy gas venting while horizontal or head-down, and the K-style inflator includes a crush-proof rubber hose for precise positioning and reliable oral inflation when needed.
