The secret of our Thermawool® is blending merino wool with just the right number of microfibers to make the ideal technical thermal fabric to breathe and manage moisture. Thermawool® has the benefits of Merino Wool with a soft fleece against your skin. Our Thermawool® Half Zip is ideal for a layering piece or on its own. It works great on its own or with the Thermawool® Pant.
