The Alto Houdi is a warm mid-layer hoodie constructed from Woolly Treemerino™, a Swedish-made fabric blending 60% merino wool and 40% Tencel® for a soft, stretchy, and highly breathable feel. Merino wool delivers natural odor resistance and insulation, while Tencel® adds structure and improves moisture transmission, making it a capable layer for hiking, skiing, or post-surf warmth. Cut in a regular fit with a refined hood design refined over years of development, it works equally well as a standalone piece or under a shell jacket in cooler conditions. The fabric is renewable, biodegradable, and recyclable, with mulesing-free traceable wool sourced from Australia.
