Aqua-Lung Buoyancy Compensators

All Aqua Lung jackets are manufactured from high density polyurethane-coated 420 or 840 denier nylon. The 840 denier material is particularly strong and abrasion resistant. Aqua Lung jackets are fitted as standard with the new high flow rate inflator and an environmentally protected mechanism. Most Aqua Lung jackets are designed to be used with single or twin cylinders, conversion requires a mechanical kit.


The Pearl i3 is best ladies BC ever built by Aqua Lung. It features an all-new air cell powered by Aqua Lung’s revolutionary i3 technology. The hybrid air cell combines a jacket style with a back inflation unit that completely surrounds the backpack. The front lobes are sleeker and low profile. The Pearl i3 retains Aqua Lung’s most notable BC features such as the integrated sports bra and SureLock™ weight system.
