Perfect apparel through three seasons of the year the Nuptse Vest remains one of the most versatile and proven down garments 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 compatible with most North Face shells so you can use it as an insulating layer beneath your favorite waterproof TNF outerwear.
