Powered by Polartec® Alpha™ Direct, the same open-mesh fleece originally engineered for the U.S. Special Forces, the ShadowFleece™ Hoodie is a new class of lightweight active-insulation by Huckberry. We fused the warmth of a fleece with the breathability of a running layer to create a hoodie built for everything from trail runs to winter training sessions. Its fabric blend dumps heat as you move, then traps warmth the moment you stop. ShadowFleece™ is lighter, softer, and more breathable than wool, dries fast, and packs to a fist without wrinkling. This fabric earned the highest test results ever recorded by the Special Operations Forces evaluation team, outperforming every insulation for breathability, durability, and quick-drying power. One layer replaces two or three, saving weight and simplifying your kit.
