Stay extra cozy and warm in our black merino wool base layer top, which merges fashion with ultimate functionality. Made from soft, non-itchy merino wool, this top offers natural breathability, moisture-wicking, and odor-resistant properties. The extended back and the integrated gaiter neckwarmer, higher in the back for easy tucking under helmets or beanies, provide added warmth and protection on cold winter days. Flatlock seams prevent chafing, and integrated thumb loops keep the sleeves in place through all your adventures.
