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, we placed inside and outside protective flaps on the Nomex® zipper tape closure and added a hidden snap closure in case of an electric arc.
