An update to one of Carhartt's most popular lined bibs, the R27, these men's overalls were designed using feedback from our Carhartt Crew. Made to hold their own through cold, wind and light rain, these bibs are the hardest-working overalls around. They're made with our heavyweight cotton duck and lined with lightweight 3M Thinsulate insulation for exceptional warmth. Reinforced kick panels lend long-lasting durability. Engineered for high warmth in severely cold conditions. See Technology section below for more details.
