The Tarcho Beanie takes its name from the Tibetan prayer flags strung across high Himalayan ridgelines, and it tackles the same kind of cold, exposed conditions. Lambswool insulates naturally while staying breathable, so the beanie holds heat in freezing temperatures without getting stuffy through all-day wear. A close-fitting knit sits snug against wind chill, and the fold-up cuff adds extra warmth when the weather turns.
