The ST35 is an excellent go-anywhere wing with the added lift for local cold-water dives but the streamlined design for dive travel. Tank slots and tank cradle are included, allowing 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 two-piece bladder is a tough 1680 Cordura nylon outer shell that prevents abrasion and punctures, coupled with a 420-denier nylon inner bladder to maintain buoyancy. The lower OPV’s easy to reach for venting gas while horizontal or heads down, and the inflation design is a K style with a rugged crushproof rubber hose for easy positioning and oral inflation should you need to.
