Our Furnace Shirt™ keeps you warm, even at 20,000 feet.
Our famous Early Winters® Furnace Shirt™ is a lofty, 8.6-oz. "polypro" top that works like your own personal heating system, providing not only incredible warmth, but humidity control as well. A great base layer for everything from high-exertion sports (like cross country skiing or climbing), to lower-impact activities back at base camp. Best of all, it's made from the latest generation of polypropylene fabric, which resists pilling and odors much better than its predecessors. Fatigue-style shirt has a three snap placket, and is heavily brushed on the inside for extra warmth and next-to-skin softness. 100% polypropylene. Washable. Imported. Tall adds approximately 2" to the sleeves and overall length.
Sizes: Unisex sizes: see fit tab for sizing.
