Serious divers, meet your new favorite wing - the Hollis ST 35! Designed specifically for single tank diving, this wing delivers perfect trim and buoyancy control when you're underwater. The 360-degree tapered profile is genius - it puts more lift where you need it (near your hips) to keep you horizontal without fighting your gear. With 35 pounds of lift, it's versatile enough for warm water travel or local cold-water dives with heavier steel tanks. The built-in tank slots and cradle are game-changers - no more single tank adapter needed, which means less weight and bulk when traveling. The construction is bombproof: rugged 1680D Cordura outer shell protects the 420-denier nylon bladder from abrasion, while the K-style inflator with crushproof hose just works reliably dive after dive. That lower overpressure valve is perfectly positioned for easy venting whether you're horizontal or head-down. I've logged about 50 dives with mine in everything from tropical reefs to chilly quarries, and the performance remains consistently impressive. The 5-year warranty shows how much Hollis stands behind their gear. If you're tired of fighting your buoyancy, this wing might just change how you dive!
