Keep warm, comfortable, and stylish with Columbia's Omni Heat technology built in to this pullover jacket. Excellent condition, only worn a few times! Please note: The tag size is a large, however, it fits me and I typically wear a small or medium. (See measurements in photos.) Pit to pit is approximately 21" ( 20 3/4") Packs up well in a stuff sack for travel or hiking! I have other omni-heat items and there's nothing better than this lining. The black polyester outer shell material is durable and can withstand harsh winter weather.
