The North Face Aconcagua Down Vest provides the core warmth you want without the poofy life jacket look of many down vests. While synthetic Heatseeker insulation resides in the shoulders and pockets, 500 fill down lives throughout the rest of the vest. The Aconcagua offers plenty of warmth and protection as a stand alone, and can also be zipped into compatible shells from The North Face when the weather gets really nasty and cold. Designed with a durable ripstop exterior that consists of over 50% recycled materials, this rugged down vest excels at running errands around town and layering for winter adventures. The Aconcagua also stows in its own left hand pocket, which makes it perfect for backpacking.
