Enchanted Impossibly Light Jacket - Women's

Weighing in at a mere three ounces, the Nike Women's Enchanted Impossibly Light Jacket might seem to disappear while you run. The ridiculously lightweight and breathable fabric blocks out chilly breezes and light rain without weighing you down or making you feel stuffy, and it packs into its own chest pocket so you can keep it in your waist pack just in case. It also has a running-specific hood that offers coverage without interfering with your visibility, and reflective details help you stay visible when you run at night.
