The SCUBAPRO S-TEK Pure Back Plate / Wing System provides a streamlined, DIR-aligned setup for technical divers who prefer twin-tank diving on scuba and underwater missions. This complete kit blends a Pure Harness with Back Plate and a Donut Wing (40 lb or 60 lb lift) to maintain stable buoyancy and precise trim in demanding dive conditions.

Key construction details focus on durability and predictable performance. The outer shell uses PU-coated 1000 Denier Cordura Nylon, paired with a 500 Denier Cordura inner bladder, while the back plate is stainless steel. The Donut Wing features a rounded profile designed to minimize air trapping, enhancing control during dives.

The harness and hardware are designed for easy handling in the field. The continuous webbing harness offers fixed-shoulder length or Extender mode for easier donning and doffing. Ergonomic features include EVO Angle webbing slots to reduce abrasion, a recessed Wing Nut Socket with S-Tek Ergo Nuts for gloves and wet conditions, and built-in carry handles. The system also includes dedicated mounting points for trim weights and argon tanks, a silicone epaulet on the left shoulder, and guide bands to keep the inflator hose in place. Additional attachment points provide versatile configuration for a complete diving gear setup.
