★ Best Pick
Warmest & Heritage: The Pendleton Board Shirt is the heritage, warmest pick — a genuine wool flannel that's the warmest, most premium, and most distinctive option here. Made from Pendleton's renowned virgin wool (the same heritage weaving behind its iconic blankets), it's substantially warmer than cotton — wool is a superb natural insulator that stays warm even when damp and regulates temperature — woven in distinctive, beautiful plaids with the durability to last decades as a wardrobe heirloom.
