The Axiom i3 combines Aqualung’s game-changing i3 side-lever inflation/deflation with the Wrapture™ Harness to deliver a truly set-and-forget fit and intuitive buoyancy control. A quick, natural thumb movement adds precise air in small or large bursts, while pushing the lever down simultaneously opens all the exhaust valves—so you can vent in any position without hunting for a pull-dump. Add the secure SureLock II weight release, GripLock tank band, swiveling shoulder buckles, and a bladder retraction system that keeps you trim, and you get a BCD that feels stable at the surface, streamlined at depth, and simple to operate even with thick gloves.
i3 one-hand buoyancy control
Aqualung’s exclusive i3+ mechanism replaces traditional inflator hoses with a low-profile side lever. Lift to inflate with fine or large bursts; push down to deflate as all exhaust valves open together. Because it’s not tied to your body orientation, you can vent while horizontal, head-down, or vertical at the surface—reducing task loading and keeping trim stable on descents, ascents, and stops.
Wrapture™ fit, streamlined profile
The ultra-thin Wrapture™ Harness pulls the cylinder tight to your body’s center of gravity for a balanced feel in the water and a natural, upright posture on deck. Swiveling shoulder buckles auto-align as you tighten webbing for a pressure-free fit, while the bladder retraction system tucks excess material during deflation to minimize drag. Add SureLock II quick-release integrated weights and a GripLock finger-safe tank band and you’ve got a fast, secure setup from car park to giant stride.
