There is no greater natural fiber for four season comfort than merino. Bearing naturally hydrophillic properties, merino manages moisture while riding and offers unrivaled comfort. Our new range of fall/winter weight base layers utilize merino based fabrics, sourced from ultrafine merino but cut in a more relaxed fit for added comfort and easy layering. At 160gsm, this mid-weight base layer adds warmth without bulk from shoulder seasons through mid-winter beneath our long sleeve jerseys or jackets, but is finished cleanly enough to act as a stand alone layer dressed up for any casual Friday (or as we call them, Friday.) Enjoy anti-bacterial, odor resistant and thermoregulating goodness in this, merino is the perfect natural fiber top.
