The Alto Houdi is a women's hooded mid-layer constructed from Woolly Treemerino™, a Swedish-made fabric combining 60% merino wool and 40% Tencel® for warmth, stretch, and breathability. Merino wool provides natural odor resistance and insulation, while Tencel® adds structure and enhances moisture transmission for active use. Cut in a regular fit, it layers efficiently under a shell jacket for skiing or wears standalone on cool-weather hikes and post-surf sessions. At end of life, the fully natural fabric can be recycled or composted.
