An update to one of Carhartt's most popular lined bibs, the R27, these men's loose-fit, insulated bib overalls were designed using feedback from the Carhartt Crew. Made to hold their own through cold, wind, and light rain, they're the hardest-working overalls around with Carhartt's heavyweight cotton duck and the legs are lined with lightweight 3M™ Thinsulate™ insulation for exceptional warmth. Reinforced kick panels, an updated, longer double knee, and triple stitching help ensure durability for the long haul. (Compatible with the Carhartt Knee Pad). 100% washed cotton duck.
