In the Carhartt FR Rugged Flex®, safety doesn't come at the cost of comfort. These men's jeans hold up to NFPA 2112 and NFPA 70E standards while keeping you comfortable long after clocking out. While the traditional cut is slim, the pants are made from denim that's flexible enough to bend, stretch, and move, and the leg opening fits over boots. Washed for instant broken-in comfort and reduced shrinkage, make these your new standard for FR comfort.
