Built for the hardest workers on the job, these work bib overalls are made from a rugged 9.7 oz cotton duck fabric with a touch lycra for durability with the added comfort of stretch. The knees, pocket edges and front bib pocket have all been reinforced with super strong polyurethane-coated polyester fabric to withstand abrasion and wear and tear. Designed with adjustable elasticated suspender straps with quick release utility buckles for a customized fit. Ankle to knee zippers with snap closures at side legs for easy on and off. Features zippered knee openings for adding knee pads and cleaning out debris. The articulated knee and a gusseted crotch construction provides a greater range of movement and flexibility while you work. You'll find plenty of room to securely store your gear in the zippered front bib pocket with additional velcro pocket and double pencil stall, spacious hip patch pockets with applied cargo pockets, large rear patch pockets and a hammer loop at each leg.
