The North Face Women's ThermoBall Hoodie is a synthetic insulated jacket for staying warm in cold, wet winter conditions. Pack it, wear it, even pull a hardshell over top, whichever way you choose, this lightweight jacket is sure to impress. Some smart person said once that imitation is the sincerest form of flattery. I don't know who exactly it was, but when it comes to ThermoBall™ powered by PrimaLoft®, this synthetic insulation certainly got the imitation part right. You see, it mimics down clusters, allowing you to compress the jacket down quite small as well as trap heat for warmth. Unlike down however, it even keeps you warm when wet, resisting moisture. How neat. An attached hood and a couple of zippered hand pockets provide the little touch of extra you need to stay cozy warm. So get outside in this ultralight phenom, staying warm whether you're hiking, skiing, camping, climbing or having other wintery outdoor fun.
