The Alto Houdi is a performance midlayer built from Woolly Treemerino™, a Swedish-made fabric combining 60% merino wool and 40% Tencel® for warmth, stretch, and natural breathability. Merino wool delivers reliable insulation and odor resistance, while Tencel® adds structure and improves moisture transmission. Designed for layering under a shell on the slopes or wearing standalone in a mountain cabin, it suits a wide range of cold-weather activities. When the garment reaches the end of its life, the all-natural construction makes it biodegradable and recyclable.
