Hollis ST System

The ST System combines most popular single tank components into one, both including the Solo harness for the ultimate in simplicity and streamlining. This kit is preassembled from the factory and includes unique components depending on the configuration. For those diving in colder waters can choose the ST System, which includes the ST35 wing, Stainless Steel Backplate 2.0 and Backplate backpad 2.0.

- ST35 Wing -
The new 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.

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 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.
