(16 kg) ST22: Designed for Warm Water Dives Aluminum Cylinders Low Lift & Maximum Streamlining Preferred ST35: Excellent Choice for Go Anywhere Wing Added Lift for Local Cold-Water Dives Heavier Steel Cylinders Still Streamlined for Travel Destinations The Hollis ST line of wings are a brand-new series for single tank diving. The design features a 360 Degree tapered profile, to increase lift towards the hips, promoting better horizontal trim in dive position while still allowing perfect surface floatation. The ST22 is designed for warm water dives in aluminum cylinders, where low lift and maximum streamlining is preferred. Alternatively, the ST35 is an excellent choice for a go anywhere wing with the added lift for those local cold-water dives and heavier steel cylinders but still streamlined enough for travel destinations. Tank slots and tank cradle are included on both models, which allows you to connect your wing and backplate 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 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. Both ST wings come standard with 3/8" threaded quick disconnect inflator hose. Welded flange and one-piece retainer for servicing without the need for tools. Elbow offset to avoid tank valve/regulator interference and streamlined hose routing. The ST22 provides 22 lbs. (10 kg) of lift and the ST35 provides 35 lbs. (16 kg) of lift.
