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.

      For work or casual wear, this polo is a great choice.
      Material Type: Recycled Polyester, Color: Port Stripe, Size: X-Large
      I really like this polo. I've been wearing it once a week or every other week since November. Its very comfortable and breathable. This polo feels like it should last a while. The fit is good. I typcally wear XL and this XL fits great. I've pruchased it in both burgundy and black so far. I definitely recommend this shirt. For work or casual wear, this will look good.
