Side-mount diving was originally conceived as a specific cave diving layout, allowing better maneuverability in small spaces. Side-mount diving has now become widespread. Scubapro has taken a modular approach to the side-mount system with this X-Tek Side-Mount LT Wing air cell. Air cell is available in two lift capacities of 25 lbs. or 45 lbs. (12 kg or 25 kg). The air cell shells are manufactured from durable 1000-D Cordura material with a strong Soltane inner bladder. Soltane is a polyurethane radio frequency (RF) welded material for. The LT Wings come standard with the Scubapro's Balanced Power Inflator (BPI) with 3/8" threaded quick-disconnect hose. The BPI has a cable activated pull dump valve assembly at the shoulder. The LT Wing comes with an attached crotch strap.
