The Kirby Morgan 37 Diving Helmet comes standard with the Quad-Valve™ exhaust system, which has less breathing resistance than the older single valve exhaust while providing an extremely dry hat. This system is recommended for diving in biologically contaminated water. Kirby Morgan's SuperFlow® 350 regulator is a proven design that provides excellent breathing characteristics over a wide range of depths.
The Kirby Morgan 37 is one of the most popular designs in the world. It's considered the standard of the commercial diving industry, as well as the U.S. Navy. Choose the Kirby Morgan 37 if you want a rugged diving helmet with a traditional design.
