When the temperatures begin to dip, this form fitting vest is the ultra-packable, lightweight, layering piece you want in your pocket. It provides warmth and wind protection across your core with mesh on the upper back to remove excess heat so you won't get too hot. An updated fit features a contoured waist and shoulders specifically designed for the female form, with binding placed around the sleeve opening to create a close fit that all but eliminates noise from flappy fabric.
