This active jacket is a perfect combination of durability, comfort and protection. The 13-ounce FR duck, made of 100% cotton, is as rugged as they come. The 10.5-ounce FR quilt lining will keep you warm in the coldest of conditions. The Nomex® rib-knit cuff and waistband seal out the cold, while the interior patch pockets with secure FR closures provide convenient storage. You will also be able to achieve a snug fit with the Nomex® drawcord on the attached quilt-lined, three-piece hood. For added protection, there is inside and outside protective flaps on the Nomex® zipper tape closure and added a hidden snap closure in case of an electric arc.For over 115 years, Carhartt has manufactured premium workwear known for exceptional durability, comfort, quality of construction, and fit that you can feel in the fabrics and see in the performance.
