The North Face Women's Flyweight Hoodie is an ultralight jacket for wind resistance on trail runs. The seriously light WindWall® fabric is so thin, it's practically see-through, but it'll provide less than 4 CFM (where 0 CFM is 100% windproof). Pull it on and set your pace on the trail, while this gives you the protection needed to move forward on blustery days. The hood adjusts to prevent it from blowing off and the zippered pockets will hold onto your glove liners when your hands get too warm. When the wind finally dies, pack the whole thing into its pocket.
