The AGIR Blackbird wing, designed for a single cylinder, is a single-bladder buoyancy compensator. The outer shell is made of durable Cordura 1000. The inner bladder is made of highly puncture-resistant Nylon 400. Its shape and 360-degree inner bladder allow gas to move easily from one side of the inner bladder to the other. This ensures simple, quick and effective release of excess gas.

Inflator with a ribbed tube for increased flow and durability, finished with a K-type head.

The overpressure relief valve (OPV) is located at the bottom of the wing. It is equipped with a nylon cord that allows the valve to be opened while wearing thick gloves and minimises the possibility of entanglement.

The OPV can be used to adjust buoyancy in a horizontal position, reducing the need for the diver to move.
