CrewBoss TREX - Technical Rescue

Raising the bar, again

The legendary quality and toughness of CrewBoss PPE is now available in a technical rescue and extrication garment system. The all new TREX line has you covered for the majority of calls that you receive as a firefighter, from MVAs, to technical rescue, to medical calls, and wildland fires.


Dual Certified

The entire TREX line is certified to both NFPA 1951 for technical rescue, and NFPA 1977 for wildland fire, making it the ideal PPE for a broad range of applications.

Stay Cool, Stay Safe

With the vast majority of on call firefighter injuries being related to heat stress, keeping your core body temperature down is just as much about safety as it is about comfort. TREX gear helps to keep you cool by providing the protection that you need for most incidents, without the heavy thermal liners found in structural PPE.

Save Your Turnouts

The TREX garment system offers a substantial return on investment by limiting the unnecessary wear and tear that occurs on your expensive turnout gear during non structural calls, and trainings.
