The Wrapture Harness System is a patented feature by Aqualung that uses swivel shoulder buckles and an ultra-thin back plate. This system prevents the BCD from riding up on the surface and keeps the cylinder close to your center of gravity out of the water, allowing you to stand up straight effortlessly.
The SureLock II is a patented weight system integrated into the Aqualung Dimension BCD. It allows for easy insertion of the weight pouch, with an audible click to confirm secure attachment. The weights can be released with a firm pull of the handle for safety and convenience.
The Powerline inflator mechanism is a time-proven airway that has been powering Aqualung BCDs for years. It offers an increased fill rate, one of the highest air flows in the industry, and is environmentally sealed for less maintenance. This mechanism provides effective buoyancy control for the diver.
The Aqualung Dimension BCD is crafted from durable, fade-resistant ResisteK material. This material ensures the longevity of the BCD and resistance to the harsh marine environment.
The Aqualung Dimension BCD offers multiple storage options for divers. It includes an adjustable chest strap, an octo-pocket on the right lobe, two large utility pockets on either side, and knife attachment points on the left lobe. It also features 4 stainless-steel D-rings and 4 plastic D-rings for attaching additional accessories.

I purchased this for my son as a gift. He likes all the bells and whistles for carrying knife, light etc and the fact it is back inflated. This will be great for future dry suit dives too!

The Aqua Lung Dimension is an outstanding BCD. The size specifications are spot on. The straps are easily adjustable and the weight pouches work seamlessly. The workmanship cannot be beat. I highly recommend this BCD.

Just purchased this BCD, it’s extremely comfortable. Even with 20lbs of weight, wreck gear and tank this BCD distributes the weight and comfort flawlessly. I enjoy the trim pockets, plentiful D rings for gear and the easy fasten system of the rapture buckles. Whether boat or shore dives this BCD is easy to don/doff, great for cold or warm water dives

Aqua Lung Dimension
By Bernard H.
The Aqua Lung Dimension is an outstanding BCD. The size specifications are spot on. The straps are easily adjustable and the weight pouches work seamlessly. The workmanship cannot be beat. I highly recommend this BCD.
The Dimension is a back-inflation style BC that incorporates Aqualung's integrated Wrapture Harness System, providing amazing comfort and stability. The Dimension is made from durable, fade-resistant ResisteK material and features the patented SureLock II mechanical integrated weight system. Wrapture Harness System f Using patented swivel shoulder buckles and a proprietary, ultra-thin back plate, the Wrapture prevents the BC from "riding-up" on the surface. Out of the water, the Wrapture keeps the cylinder close to your center of gravity and transfers the weight to your hips allowing you to effortlessly stand up straight. SureLock II Mechanical Weight Release System (patented) f allows you to easily insert the weight pouch and an audible "click" lets you know the weights are secure in the BC. Once engaged, the weights can be released with a firm pull the handle.
High pressure (HP) hose routings through the back keep your entire kit low profile thus minimizing drag. The low-profile flat valves reduce drag when moving through the water. A bladder retraction system is used to pull in the sides of the bladder during deflation. This keeps unit streamlined and reduces drag. Adjustable chest strap for personal comfort. A clever octo-pocket on the right lobe secures the octopus while keeping it accessible and visible throughout the dive.
Two large, easy-to-access utility pockets are found on either side of the Dimension. Easy-to-access knife attachment points on the left lobe accommodate many of the Aqualung knives. Features 4 stainless-steel D-rings and 4 plastic D-rings (1 is located inside the left pocket) for all your accessories. Right shoulder pull dump provides an additional dumping option. Rolled neoprene neck collar for comfort. Non-releasable weight pockets on the back of the BC help the diver achieve proper positioning in the water. All sizes can hold up to 30 lbs. (13.5 kg) of lead weight with 20 lbs. (9 kg) releasable.
Buoyancy control is provided by the Powerline inflator mechanism. Powerline is the time-proven airway that has been powering Aqualung BCs over the years. From its over-molded lower unit and stylish hose to its cable activated rapid exhaust, what's not to like? Increased fill rate; now one of the highest air flows in the industry. Environmentally sealed unit for less maintenance. Integrated hose clips attach to the hose to lower profile and streamline gear. Cable activated rapid exhaust at the top, simply pull down on lower unit to dump air. Inflator includes dust cap cover for QD nipple. Inflator comes with a 3/8" threaded low pressure QD hose. BC provides 29 lbs. to 42 lbs. (13.2 kg to 19 kg) of lift. BC comes with an owner's manual.
