The Carhartt Men's Relaxed Fit Mid-Rise Rugged Flex Duck Dungaree Pants have a straight leg opening, and are built for comfort and freedom of movement. The heavyweight duck fabric has the same look and feel as Carhartt's classic duck, with a bit of added flex for mobility. Built with Rugged Flex stretch technology, these pants sit at the waist, and feature a comfortable, relaxed fit through the seat and thigh, giving you more room to move. And, with heavy-hauling, back pockets, multiple tool pockets, a hammer loop, and strong sewn-on-seam belt loops, they provide all the carrying power you'll need. Carhartt Rugged Flex technology moves and stretches with you throughout the day so that whatever you're doing, it's easier to do. Rugged Flex garments must meet the Carhartt's defined standards for stretch, recovery, and durability, so when you put on a Rugged Flex garment, you know it won't let you down. You'll find Rugged Flex in Carhartt shorts, shirts, pants, jackets, and boots because you need gear that helps you move, not gear that holds you back.
