The Alto Houdi is a performance midlayer crafted from Woolly Treemerino™, a Swedish-made fabric blending 60% merino wool and 40% Tencel® for a warm, stretchy, and lightweight feel. Merino wool delivers natural insulation and odor resistance, while Tencel® adds structure and enhances moisture transmission for sustained comfort across varied conditions. Designed for layering on cold ski days, post-surf warmth, or cabin use, it works as a versatile next-to-skin or standalone piece. When the garment reaches end of life, the all-natural fabric is fully recyclable and biodegradable.
