In addition to the 4-way stretch nylon that offers maximum flexibility when picking up the pace during a run, this jacket has a DWR treatment to keep you dry in summer rain showers or light snow. The partial mesh lining increases breathability for added comfort while blocking chilly gusts of wind. With zipped hand pockets, you have room to store essentials like credit cards and car keys. Fitted with an elasticated hood, cuffs, and hem for a secure fit, the Flash Sky Jacket for women is ideal for year-round endurance sports.
