The Alto Hat is knitted from Woolly Treemerino™, a Swedish-made fabric combining 60% merino wool and 40% TENCEL™ Lyocell for a soft, stretchy, and highly breathable fit. Merino wool delivers natural warmth while the Lyocell fiber adds structure and improves moisture transmission, making it suitable for active pursuits like skiing and ice skating as well as daily wear. The hat uses only natural fibers — no synthetic blends — resulting in a garment that is fully biodegradable and recyclable at end of life.
