Just because the temperatures drop doesn't mean your performance has to as well. These Men's DuraTech Renegade FLEX Insulated Bib Overalls are made of comfortable yet strong FLEX duck fabric equipped with a Durable Water Repellent (DWR) finish. Couple that with the zip-to-waist 2-way zipper and you've got safety and comfort to spare. Be prepared for any change in work conditions with these Insulated Bib Overalls. We've anticipated this for you by adding an easy-access storm flap. There's also reinforced triple-needle stitching, durable double knees with pad openings, and an adjustable hem to keep you warm in all kinds of weather.
