The Scubapro S-Tek Pro System's revolutionary design is built tough and loaded with features, helping to make your time at depth more comfortable and enjoyable. Designed for both utility and comfort, this system features 3D formed back plate with harness that includes adjustable Tek LOC shoulders to ensure a snug fit and molded Monprene pads that provide cushioning without creating bulk or inherent buoyancy. For convenience, the system is sold as a comprehensive kit including the Pro Harness with Back Plate, 30 lbs. (13kg) lift Donut Wing and Single Tank Adapter.

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.

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.
