Outdoor Research Alpine Onset Merino 150 Baselayer Bottom - Women's Stardust Heather, M

The Alpine Onset Merino 150 Bottoms are our go-to base layer for cold-weather adventures, offering breathable warmth and moisture-wicking performance. Made from a soft, non-mulesed merino wool blend, these bottoms move with us while keeping us dry and comfortable during active pursuits. With flat-seam construction to prevent chafing and UPF 30 for added sun protection, they're perfect for long days of hiking, climbing, or skiing in the backcountry.
