Scubapro S-Tek Pure System Harness Donut Wing 40 lbs. (18kg) Lift

Scubapro's S-Tek Pure Back Plate/Wing System was designed for technical divers who subscribe to the DIR (Doing It Right) approach to streamlined and minimalistic equipment configurations. For convenience, the system is sold as a comprehensive kit including the Pure Harness with Back Plate and 40 lbs. (18kg) lift Donut Wing.

The Pure Harness is a continuous webbing harness that provides a custom, individualized fit. Configuration options include fixed-shoulder length harness for ultimate simplicity or extender mode that allows the shoulder straps to extend for easier doffing & donning. Stainless steel waist buckle allows for a full range of adjustment. Branded silicone epaulet on the left shoulder and branded silicone guide bands keeps inflator hose and straps in place. Two pre-bent D-rings on the shoulders, one D-ring on the waist, and two D-rings on the crotch strap are provided for clipping on extra gear.

The S-Tek Pure Back Plate is a 3D formed back plate that features a softened organic shape, curved central profile and fully radiused edges for greater comfort. EVO Angle webbing slots allow for a more natural webbing routing that increases diver comfort and reduces abrasion. Recessed wing nut socket features S-Tek ergo nuts that are ergonomically designed to be used with cold, wet or gloved hands, easy to tighten/loosen and flush mounted to prevent suit abrasion. Recessed wing nut socket is also compatible with standard wing nuts. Back plate provides mounting points for trim weights, an argon tank mounting point and a convenient built-in carry handle. The Pure Harness and stainless-steel back plate weigh 6.83 lbs. (3.1kg).

The donut wing is constructed of durable 1000D Cordura outer shell and 500D Cordura inner bladder. Improved rounded profile reduces air trapping. Wing features an elliptical EPDM corrugated inflator hose and Scubapro's K-Style Balanced Power Inflator (BPI). Scubapro BPI mechanism: Scubapro's BPI provides a high inflation speed, especially at depth. Inflator has different shaped inflation and purge buttons for easy use even in extremely low light or murky water conditions. Inflator is also equipped with a rapid pull dump mechanism with cable pull for easy deflation of the air bladder. Included with the inflator is a 3/8" threaded low-pressure hose for attachment to the first stage regulator. For trimming buoyancy when diving in an inverted position the donut wing has a left lower overpressure relief/pull dump valve with pull cord. The wing weighs 2.43 lbs. (1.1kg).
