Our Carhartt 101494 Jefferson Vest is constructed of 60% cotton/40% polyester canvas with Rain Defender™ durable water-repellent finish. Lined with 80gram 3M™ Thinsulate™ insulation, it is 30 percent lighter than other Carhartt vests, yet with the same warmth and durability. Other features include a mock-neck collar with zip through, a left-chest pocket with media port to inner garment, drop tail and triple-stitched main seams. It won’t disappoint! Replaces style #100002.
