The Roark Nordsman 2. 0 Shirt blends 90% polyester with 10% wool to bring real cold-weather warmth without the itch or bulk of a heavier wool flannel. A heavyweight brushed fabric and relaxed fit make it comfortable enough to wear solo on cool days or layered under a jacket when the temperature drops further. A snap-front closure and dual chest pockets keep it practical, whether it's covering a trail hike or a walk around town.
