The Men's Carhartt Super Dux Relaxed Fit Insulated Bib Overall is built for working or playing outdoors during chilly temperatures. Designed for comfort, durability, and warmth, the Carhartt Super Dux Bibs are made from high-quality nylon and feature both sherpa and insulated lining to help trap and retain body heat. With Rain Defender® and Wind Fighter® technology, the Carhartt Super Dux Bibs shed precipitation to keep you drier for longer as well as block out the wind for added warmth. With a zip-to-knee leg opening and adjustable suspenders, you'll be able to customize the fit and ventilation level as needed.
