The Carhartt® Flame-Resistant Duck Bomber Jacket is an all-season jacket designed to last. It resists flash fire and arc flash, but never hard work. Made to Carhartt standards with 13-oz. 100% cotton flame-resistant duck, a tightly woven material that is water-, wind- and snag-resistant while remaining breathable. The 11.5-oz flame-resistant quilt lining keeps you safe and warm. The triple-stitched seams give this jacket the durability you expect. Designed to keep you safe on the worksite, the jacket is NFPA compliant and UL classified to NFPA 2112. It is also HRC 4 with an ARC rating of 54.3. The pair of inside patch pockets have flame-resistant hook-and-loop closures and are perfect for holding onto a phone or keys. A pair of front slash pockets are perfect for keeping your hands warm, while the Nomex rib-knit cuffs and wristbands seal out wind and cold and provide heat and flame resistance. The brass zipper features Nomex zipper tape with inside and outside protective flaps and a hidden snap closure for electric arc protection. An optional hood (sold separately) can be added for extra protection and warmth.
