An updated version of Carhartt's popular R27 lined bibs, these men's overalls were designed to hold their own through cold, wind and light rain. They're made with heavyweight cotton duck and lined with ultra-light 3M™ Thinsulate™ insulation through the legs for exceptional warmth without the bulk. Adjustable elastic suspenders with webbing sliders and side button closures with stretch panels ensure a more precise fit. Replaces R27.
