When chill sharpens, warmth steadies. 108 grams of FuzzFleece™ AD protection. Adaptive insulation for unpredictable explorations.

Engineered with Polartec® Alpha® Direct, FuzzFleece™ AD is active insulation built for motion. Lofted fibers sit on a breathable mesh core, holding warmth without weight.

Hydrophobic by design: it wicks, dries fast, and keeps insulating even when damp. Adaptive by nature: comfort in cold starts, breathability when intensity rises.
