The North Face Women's ThermoBall Insulated Vest provides ample warmth without weighing you down. Constructed with a nylon shell that's treated with a Durable Water Repellant, this insulated vest repels light rain and snow showers from dampening your outdoor adventures. The ThermoBall Insulated Vest really shines as a toasty, highly versatile midlayer under a waterproof shell. Wear it skiing, climbing, or bring it with on trips into the backcountry. The vest's ThermoBall insulation takes care of business, shielding you from freezing temperatures with its down like clusters of synthetic insulation. However, unlike down which loses insulating properties when it's wet, ThermoBall insulation won't sacrifice warmth once moisture seeps in. This makes it an exceptional choice for layering on wet winter days and soggy autumn excursions. In addition, the vest's feminine quilt pattern delivers a chic, streamlined style that makes it easy to throw under a jacket and over a base layer.
