The Oceanic Atmos Hybrid Air-Cell BCD is a two-in-one, full-featured buoyancy compensator designed for scuba diving. Its hybrid rear-inflation bladder shifts air to provide maximum lift and helps maintain proper orientation on the surface and underwater, making it a versatile piece of diving gear.

Designed for reliable buoyancy control in scuba diving, the Atmos integrates 20 lbs (9 kg) of integrated weight in the Pinch, Release system and 10 lbs (4.5 kg) trim, a padded backplate with extended lumbar support to transfer tank weight onto the hips, and three over-pressure relief valves to fine-tune buoyancy. Crucial areas are constructed of 1000D denier Cordura fabric, and the design includes two large zippered pockets with knife mounting grommets and an adjustable depth-compensating cummerbund. Lift capacity: SM 30 lb (130 N); MD 35 lb (155 N); LG 45 lb (200 N); XL 55 lb (240 N).
