From Backcountry

In any season or sport, when we need added warmth, we start our layering system with the Smartwool Classic All-Season Merino Base Layer. Overnight summer backpacking trips, shoulder season hikes, and active skintrack ascents keep us on our feet year-round, and merino wool helps us combat the chill without letting us overheat or weighing us down.
