The Nike AeroLoft Flash Women's Running Gilet features a reflective graphic on the front to help you stand out. The 800-fill feather-down insulation provides lightweight warmth. When you get too hot, the gilet can be packed into a zipped pocket and held with an attached strap. This version features Nike Flex fabric on the sides and back so you can move freely. Stay Dry and Warm A water-repellent finish on the body helps keep rain out. The baffles on the front and sides of the back feature sections of 800-fill down insulation. The fill has a DWR (durable, water-repellent) finish that repels moisture to help reduce clumping. Breathe Easy Perforations between the insulated sections and throughout the back allow air to flow and body heat to escape, helping to regulate your temperature. To help keep wind from hitting the front of the body directly, a thin liner backs the front perforations. Pack Away When you get too hot, the gilet can be packed into a zipped pocket and held with an attached strap.
