Warm and cozy merino wool insulation garment. Men’s Alto Halfzip in all natural 60% merino wool and 40% TENCEL™ Lyocell is a perfect alternative to synthetic fleece.

Made from Woolly Treemerino™, a Swedish made warm, stretchy and lightweight fabric in merino wool and TENCEL™ Lyocell.

TENCEL™ Lyocell is a fiber made from cellulose that gives the fabric structure and better moisture transmission. Merino wool provides warmth and is naturally odor resistant.

Together they make up a garment that is both highly functional and completely biodegradable.
