Scubapro S-TEK Donut Wing 40 + S-TEK Pro Harness SS + Back Shoulder Waist Pad

The Scubapro S-TEK Donut Wing 40, paired with the S-TEK Pro Harness SS and Back Shoulder Waist Pad, provides a rugged, modular platform for scuba and technical diving. The 40 lb donut wing offers reliable lift for underwater buoyancy control, while the 3D formed back plate with radiused edges enhances comfort and stability during extended dives.

Designed for durable diving gear performance in challenging environments, this system features molded Monprene pads for shoulders, waist, and back; adjustable shoulder buckle and D-ring heights to fit different torso lengths; and EVO Angle webbing slots for natural routing and reduced abrasion. The recessed Wing Nut Socket with S-Tek Ergo Nuts enables easy adjustment even with cold, wet, or gloved hands. The back plate includes trim weight mounting points, argon tank mounting, and a built-in carry handle, with branded silicone epaulets and guide bands to keep inflator hoses and straps in place. Lift capacity is 40 lb (18 kg), supported by a 6‑D‑ring layout and a total weight of 9.612 lb, all constructed from PU‑Coated 1000 Denier Cordura Nylon with a Stainless Steel back plate—designed for underwater use and technical gear setups.
