Light, fast and technical, Polartec®️ Alpha®️ insulation cuts a cold morning chill yet breathes well during fast-paced activity.

Matched to constant training—for trips, tours or ultras—our breathable active insulator is light, fast and technical. Polartec® Alpha® Active 60g insulation cuts a cold-morning chill yet breathes deeply and keeps the interior dry during high-output activity. The stretch gusseted underarm enables free-ranging mobility, while sleek construction detailing gives it a superfast feel on the trail or on the skintrack. A quick-draw hood cinches down fast when storms descend and a ripstop shell sheds light weather with a lasting DWR Finish. Key pockets stow critical items.
