These Carhartt Duck Bib Overalls are an updated version of the popular R01 Bibs. The Carhartt design team solicited feedback from real-life workers who provided suggestions on enhancements. 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 Carhartt gear day-in and out. Constructed using heavyweight, durable cotton duck that handles hard work like a champ.
