Overview

Breathable active insulation for fast-forward activity and internal climate control.

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.

Materials

Shell

Meridian™ AP Stretch Mini-Ripstop, 100% Nylon, 20 denier, 49 g/m2 with DWR Finish

Meridian™ AP is a 20 denier Mini-Ripstop Nylon with mechanical stretch by construction. A DWR finish makes this fabric both highly water resistant and extremely breathable while maintaining excellent wind resistance.

Insulation

Polartec® Alpha® Active Insulation, 54% Recycled Polyester, 46% Polyester, 60g/m2

Alpha® is a 100% polyester knit active insulation that eliminates the need to shed layers while on the move. Designed to regulate core body temp during dynamic and static activities, Alpha® technology keeps moisture vapor moving freely through the fabric, increasing the overall air exchange and speeding up dry times. A DWR coating provides water resistance, increasing this fabric's performance in the most challenging environments.
