With a full-length side-zip for easy removal or layering, the new Alpha Pant is a clutch piece for frigid resort laps, long sled-skiing days, chilly alpine starts, or relaxing at a backcountry hut. Featuring the lightweight, breathable, and quick-drying Polartec Alpha, the active insulation will maintain critical warmth for your knees and legs without bunching at your boots. Wear these crop pants under (or over) your shell pants for additional comfort and safety on cold days.
