Meet the Frost Unisex 3L Jacket: Your Command Center for the Mountain. Engineered for the elite, this jacket features a professional 3-layer fully-taped waterproof shield (20,000mm/15,000g) and a Rudolf BIONIC-FINISH® ECO repellant surface to actively defy blizzards and moisture. Its 40GSM DuPont insulation traps core warmth without bulk, while strategic under-armpit vents release excess heat on demand. From the 3D, helmet-compatible hood that guarantees clear vision to the snow-skirt, knitted thumb holes, and fortress-like secured pockets, every detail is a calculated defense against the elements. This is All-Mountain dominance, perfected.
