Crafted from a blend of Nylon and Polyester, this practical windproof jacket features essential reflective materials for night activities along the chest, sleeves, and hood. Woven with ultra-fine 20D yarns, its 380T down-proof material provides wind resistance, enhanced by a water-resistant DWR coating. Weighing less than 195 grams, it folds into a palm-sized pouch, with a hidden chest zip mesh pocket for convenience and air circulation.
