Carhartt Men's Loose Fit Firm Duck Double-Front Utility Work Pant New Without Tags 100% Cotton Care instructions Machine Wash Warm Hard work in, hard work out. Behind every pair of Carhartt® Loose-Fit Firm Duck Double-Front Work Dungarees for Men are 61 pairs of hands that cut, sew, hem, and triple-stitch the 28 pieces that form the classic B01. Before they even show up on the jobsite, they've already lived through several shifts of hard work. These men's dungarees have changed very little since they were introduced in 1939. They feature a rugged design featuring double-layer knees with clean-out bottoms that can hold kneepads, a generous fit through the seat and thighs, and straight leg openings. Heavyweight firm-hand duck is the most durable canvas out there and holds up extremely well to hard use. These Carhartt work pants also sport heavy-hauling back pockets, multiple tool and utility pockets, and a left-leg hammer loop. 12-oz. 100% ringspun cotton-duck canvas.
