Product Description

The Aqua Lung Dimension i3 BCD is a feature-rich, extremely comfortable, back inflation style BCD that incorporates Aqua Lung’s patented i3 inflation/deflation system. It is light enough to use as a travel BCD, and sturdy enough to hold enough weight to dive with a Dry Suit. All-in-all this is a fantastic BCD.


The i3 system provides easy, one-touch control for inflation and deflation. This eliminates the traditional inflator that dangles at the end of a corrugated hose, making the BCD feel more streamlined and comfortable to dive. The i3 system is simple and intuitive - just lift up on the lever to inflate and push down on the same lever to dump air. Also, when you push the lever down, all the dumps, upper and lower, open at the same time, meaning it doesn't matter which way you are situated in the water (head up or bum up) if you push down the leaver then air will dump. 

As a safety feature there is a pull down oral inflator is easy to deploy, use and stow. And a right shoulder pull dump provides an additional dumping option.


Flat e-valves are very streamlined and effective. They are also "one-way" which keeps water out!


The Dimension BCD's amazing comfort and stability come from the integrated Wrapture™ Harness System, which provides amazing comfort and stability.

Out of the water, the Wrapture system keeps the cylinder close to your centre of gravity and transfers the weight to your hips. The result is the ability to stand up straight with a cylinder that is perfectly vertical.


Integrated weights are held securely in place with SureLock II mechanical weight system. 

SureLock II Mechanical Weight Release System (patented) – provides a safe, single-pull release. Inserting weight is as simple as insert and “click”. With SureLock, your weights are secure in the BC. Once engaged, the only way to release the weight is to pull on the handle.


HP and MP hose routings through the back keep your entire kit low profile thus minimizing drag, and a clever octo-pocket on the right lobe keeps the octopus accessible and out of the sand. The octopus remains visible and accessible throughout the dive.


The Dimension i3 BCD is made from durable, fade-resistant materials and comes in a black/charcoal color combination. A bladder retraction system is used to pull in the sides of the bladder during deflation. This keeps unit streamlined and reduces drag. An adjustable chest strap can be raised or lowered on a rail system. This not only ensures a good fit but also keeps the strap from running across the top of a drysuit valve.

It features a 'pocket within a pocket' – A small security pocket is found on the flap of a larger drop-down pocket. Knife attachment points are found on the left lobe which will accommodate many of the Aqua Lung knives. This location provides easy access to the knife. The Dimension BCD features 4 angled, stainless steel D-rings and 1 plastic D-ring for all of your accessories, plus a rolled neck collar for comfort.

Non-ditchable weight pockets on the back of the BC help the diver achieve proper attitude in the water, and all sizes of the Dimension i3 BCD are capable of holding up to 30 lbs / 13.5 kg of lead weight.


A female version is available, called the Aqua Lung Lotus i3 BCD.
