Our Carhartt jeans have a comfortable fit through the seat and thigh, strong sewn-on-seam belt loops and are made of 15-oz, 100% cotton washed denim. The logger jeans have a hammer loop, lots of pockets and double fronts with openings for knee pads. Each pair of the original fit duck double-front dungarees feature 28 pieces of hand-cut triple stitched material assembled by 61 pairs of hands in a rugged design that has changed very little since their introduction in 1939.
