Patented first in Italy in 1997, then in the USA in 2001, Mares AIRTRIM® is considered the most intuitive and accurate system for buoyancy control on the market. Thousands of divers around the world know the AIRTRIM integrated buoyancy control system is "always where you expect it to be".

This first and only pneumatic system (patented) revolutionizes and simplifies buoyancy control by allowing precise and immediate buoyancy adjustments from any position, under any condition. By eliminating the bulky corrugated hose and providing two oversized buttons always at hand, divers enjoy truly intuitive and ergonomic control.

By utilizing the "Twin Exhaust Valve" technology developed and patented by the Mares research laboratories, the AIRTRIM® deflation button simultaneously opens both of the pneumatic exhaust valves, allowing the BCD to deflate regardless of the diver's underwater position with virtually no water entry into the BCD. Accurate buoyancy control has never been easier.

MARES is the only Scuba diving company to offer a complete line of AIRTRIM jackets, such as the Dragon AT, the VECTOR 1000 AT and the newly introduced and attractively priced ORIGIN SPORT AT (Coming June 2007). This allows the consumer to select the jacket of their choice combined with the most advanced buoyancy control system in the industry.
