The Alto Pants are built from Woolly Treemerino™, a Swedish-made fabric combining 60% mulesing-free merino wool with 40% EU Ecolabel-certified Tencel®. The merino provides natural warmth and odor resistance while the Tencel® adds structure and moisture transmission, making these pants an effective mid-layer or standalone piece in cold conditions. Cut in a regular tapered fit with zippered side pockets and a drawstring waist, they transition easily from ski touring to post-surf warmth to cabin wear. The fabric is fully renewable, biodegradable, and recyclable at end of life.
