The Military Wool 5 Button Sweater is a great choice for the outdoorsman looking for warmth or for casual wear. The five oversized button closure is both effective and handsome. The ribbed waist and sleeve cuffs add to the comfort level and heat retention. It looks sharp, and yes, of course it's warm. Incredible quality U.S.A made Military Issue style. These are the authentic fatigue sweater first worn by Troops in WWII. 100% wool, rib knit cuffs and waist. Recommended dry clean or hand launder.
