Warmth that packs down. The Therma-FIT ADV Vest in black is engineered to regulate temperature and repel moisture, proven on desert expeditions where conditions shift fast. Nike's smart fabric technology keeps you insulated when you need it, then folds compactly into its own internal pocket when you don't. Lightweight layering that goes wherever adventure takes you.

Body: 100% nylon. Lining/fill: 100% polyester.
