About the Gen II Program

The Gen II system created in conjunction with the US Department of Homeland Security, the Army’s Natick research center, and numerous other government agencies. The goal of the program was to develop garments that could offer optimal protection against the risks faced by modern wildland firefighters. Flame resistance was a priority, but a high emphasis was also placed on breathability to reduce the risk of heat stroke and exhaustion in warm environments.

The program set high standards, all of which are met or exceeded by the CrewBoss Gen II Garment System.
