The Hollis DT line of wings are another brand-new series designed for double cylinders. The DT50 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. While the DT45 Dual features a more consistent 360 Degree floatation for lighter aluminum cylinders with a redundant air cell. Target audience for the DT45 dual is warm water, banded aluminum cylinders in a wetsuit where backup inflation is mandatory. While the DT50 is focused on the dedicated dry suit 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 internally urethane laminated with radio frequency (RF) welded seam inner bladder to maintain the buoyancy. The lower OPV (single DT50 & dual DT45) are 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. Both DT wings come standard with 3/8" threaded quick disconnect inflator hose(s). Welded flange and one-piece retainer for servicing without the need for tools. Central elbow to avoid tank valve/regulator interference.Both DT wings come standard with 3/8" threaded quick disconnect inflator hose(s).
