The Polartec Classic 300 cold weather jacket is lightweight yet warm, but not bulky. That makes this well-made jacket non-constricting so your arms can move freely. This is considered a jacket but it is warm enough to be a coat. Made out of 100% polyester circular knit terry, double-sided, heavy weight fleece. Front opening with a two way zipper closure. Zippered openings under both arms for ventilation. Two internal upper chest pockets, two lower outer hand warmer pockets with zipper openings. Since this jacket is so lightweight yet warm, it is an excellent choice for the layering of clothes in extreme cold conditions. Unused. NSN: 8415-01-461-8341.
