The Spyder Charge Women's Jacket is a very high end waterproof breathable jacket with zip off sleeves. This ski and snowboard jacket has lots of separate pockets for radios, phones, goggles, ski pass, data cards etc. The water repellant finish is Spylon+. Spylon+ is a durable water repellent finish (DWR) applied to the fabric exterior to prevent the garment from absorbing surface moisture. Spylon+ is a top-rated performer retaining 80% effectiveness after 50 washings. It also guards against water and oil-based stains. The body insulation is Thinsulate 100gm and the sleves are Thinsulate 80gm. Thinsulate insulation is constructed of unique micro fibers, about ten-times smaller than in other synthetics. These efficiently trap insulating air, reflect radiant body heat and deliver warmth two-times greater than down and other polyester insulations when equal thicknesses are compared. Thinsulate is a trademark of 3M.
