Aqualung Dimension Back-Inflation BCD

By Aqualung | Versatile All-Environment BCD | Back-Inflation Wing & Wrapture™ Harness

Engineered as the ultimate crossover BCD for both tropical travel and local cold-water diving, the Aqualung Dimension Back-Inflation BCD delivers effortless buoyancy control and horizontal trim in any underwater environment. By positioning the air cell behind you, the Dimension leaves your chest completely uncluttered for maximum freedom of movement. Built with Aqualung’s body-hugging Wrapture™ Harness System, it supports heavy steel cylinders comfortably across your hips for Pacific Northwest drysuit diving while streamlining your profile for warm-water reef adventures.

Key Performance Features

• Back-Inflation Wing Design: Keeps air cell behind your back for perfect horizontal trim, hydrodynamic swimming, and an open, comfortable chest area.
• Wrapture™ Harness System: Swivel shoulder buckles and refined backplate architecture transfer tank weight directly to your hips and eliminate cylinder wobble.
• SureLock II Mechanical Weight Release: Single-pull integrated weight pockets click in firmly with visual confirmation and ditch smoothly during emergencies.
• GripLock™ Tank Band: Micro-adjustment macro preset system locks your scuba cylinder down tight without wetting the nylon webbing strap.
• ResisteK™ Fade-Resistant Fabric: Advanced fabric construction resists scuffing, sun fading, saltwater abrasion, and chlorine.
• Streamlined Flat E-Valves: Low-profile dump valves reduce underwater drag while an integrated bladder retraction system pulls in the sides during deflation.
