It’s warm enough for solo wear around camp and breathable enough to layer under shells on frigid days in the backcountry.Designed with a performance fit that hugs close without restricting, these bottoms move effortlessly whether we’re setting up basecamp or bootpacking to a powder stash. With its premium feel and insulating power, this is a cold-season essential we wear as soon as the frost rolls in.
