The Alto Houdi is a warm, stretchy mid-layer hoodie made from Woolly Treemerino™, a Swedish-made fabric blending 60% mulesing-free merino wool and 40% Tencel®. Merino provides natural insulation and odor resistance, while Tencel® adds structure and improved moisture transmission for active use. Cut in a regular fit, it works equally well layered under a shell jacket on the mountain or worn standalone on cool-weather hikes and post-surf sessions. When the garment reaches end of life, the all-natural construction means it can be recycled or composted.
