The Ultralight Down Jacket is our lightest-weight insulating full-zip down layer, with a slim silhouette for thermal efficiency and a superlight, water-resistant 100% nylon shell. The lightest weight, strongest shell fabric we’ve ever engineered for down garments; with a Deluge® DWR (durable water repellent) finish. 800-fill-power premium European goose down for low-bulk warmth. Variegated channel construction stabilizes insulation and also allows the use of less down, creating an elegant, low-profile garment. Zippered pockets: Two handwarmers, one chest. Drawcord hem seals out cold and spindrift. Self-fabric stuff sack. Shell and lining: 0.8-oz 10-denier 100% nylon ripstop with a Deluge® DWR (durable water repellent) finish. Insulation: 800-fill-power premium European goose down. 218 g (7.7 oz) Made in China.
