The Alto Hat is knitted from Woolly Treemerino™, a Swedish-made fabric combining 60% merino wool and 40% TENCEL™ Lyocell — delivering natural warmth, stretch, and breathability in a lightweight 40g package. The merino provides reliable insulation and next-to-skin softness, while the Tencel fiber adds structure and enhances moisture transmission, making it suitable for active use on the ski slope, the ice rink, or the daily commute. True to Houdini's material philosophy, no natural and synthetic fibers are blended, resulting in a hat that is both biodegradable and recyclable at end of life.
