For season-long shredding and our other favorite winter sports, the Backcountry Cedars Rws Merino Midweight Baselayer Bottom delivers the warmth we want. Midweight merino wool fibers offer insulating, wicking, and temperature-regulating tech in a super soft and naturally odor-resistant package. And even better, the wool is Wool Standard-certified, so you know it came from a farm where they care for their land and animals.
