The Hollis ST line of wings are a 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 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 ST35 provides 35 lbs. (16 kg) of lift. 

The Hollis 2.0 Backplate Line is the foundation for the new Hollis technical harness systems. They feature improved ergonomics for a more comfortable fit, but are still short enough to fit smaller frame divers. The Stainless-Steel version it is laser cut and CNC bent, which give this awesome new appearance. Geometry of the webbing slots is similar to Hollis prior design to ensure reverse compatibility for all Hollis buoyancy accessories, so if you have a current Hollis harness, wing or weight system, this new plate will fit. The stainless weighs in at 6.5 lbs. (2.85 kg), is 304 stainless-steel and has a bead blast finish that is electropolished and chemically passivated to avoid scratching, so it will continue to look this way after many years of use. Stainless steel plate is 0.16" (4mm) thick.
