Constructed with the innovative High Strength Commando Twill™ fabric and inherently FR fibers, it is incredibly light yet strong. The engineered stretch allows for a slimmer cut while maintaining maximum mobility. Pockets are low profile and engineered to reduce bulk while still allowing room for all essential gear. Flame tested on NC State’s Pyroman (in accordance with ASTM F1930) for an optimized thermal protection level. Designed for use with Crye Precision removable AIRFLEX™ Impact Combat Knee Pads (sold separately), can be matched with G4 FR Combat Shirt, and Aclima Hotwool Pant or Aclima Woolnet Pant as base layers (sold separately).
