The Burton Expedition Wool Pants may look like a run-of-the-mill base layer, but slide them on and you'll instantly notice the difference. drirelease® wool is impeccably warm and unlike other wool, feels super nice against your skin. Pair this with thoughtfully-placed softlock seams, expedition-weight paneling for warmth where it matters most, and a women's specific contoured waistband, and the Burton Expedition Wool Pants are ready to see you through your coldest, most technical missions this season.
