NWOT, never worn men’s 38x30 duck bib. An update to our most popular unlined bib, the R01, these heavyweight men's bib overalls were designed using feedback from our Carhartt Crew. Every detail, from the front-to-back kick panel on the cuffs to the extra stretch around the waist, was informed by the hardworking people who wear our gear day-in and day-out. The heavyweight cotton duck material makes them dependable and durable. Elastic suspenders, a double layer at the knees, and ample pockets provide even more durability and functionality. Compatible with the Carhartt Knee Pad.
