You're looking at the most versatile vest in the entire North Face collection. It's made with a Z-Ripstop shell fabric that's wind resistant water repellent and completely down proof. Lightweight highly compressible 700-fill down maintains thermal performance while sewn-through construction keeps the down from shifting and creating cold spots. Best of all the Nuptse Vest is Zip-In compatible so you can use it as an insulating layer beneath your favorite waterproof North Face jacket.
