When the forecast is frigid, pack the heavyweight warmth of the Core Merino 330 Hoodie. It features our warmest-weight merino wool to keep you warm in the coldest conditions. Temperature-regulating merino wool has an exceptional warmth-to-weight ratio to keep you warmer with less bulk, and the contoured hood with a built-in facemask offers additional comfort and concealment. Merino wool also resists odor to help you stay undetected, and our ArmorSpun merino wool is reinforced for improved durability. And to make sure excess moisture doesn’t leave you wet and cold, we added a synthetic interior that quickly moves sweat off your skin and through your system to keep you dry and warm.
