Evaluation of the Joint Service General Purpose Mask, XM50

Abstract

The Joint Service General Purpose Mask (JSGPM) is the next generation chemical protective mask intended to replace the MCU-2 and M-40 series masks. Developmental testing and user assessment of the XM5O, a variant of the JSGPM, indicated that the XM5O lacked sufficient fogging mitigation1 and sweat reduction capabilities. Lens fogging and sweat accumulation in the mask degrade user confidence, impose a physiological burden upon the user, and can seriously degrade operational effectiveness. These performance shortcomings resulted in joint service concern,2 and design changes to the mask were made. In 2003, a field evaluation3 indicated that the sweat reduction issues had been resolved, but the evaluation was limited and did not challenge the XM5O's ability to mitigate fogging.
