M50 JSGPM. Protecting today’s warfighter with tomorrow’s technology.

The design and development by Avon of the M50 mask has resulted in the most advanced general service respiratory protection mask to date, offering significant improvement in comfort, usability, operational effectiveness and protection.

A revolutionary cast flexible visor offers wide, optically correct vision together with being impact and scratch resistant.

Close fitting, curved conformal filters offer improved weight distribution and reduced breathing resistance, as well as enhanced protection against toxic industrial agents. An integrated Electronic Communication Port allows for an internal microphone for communication systems. In addition, a high flow hydration connection enables quick and easy fluid intake.
