Super lightweight and packable, the Mountain Hardwear Women's Nitrous Hooded Jacket is top-notch when it comes to a high warmth-to-weight ratio. Made with down proof, Sensor(R) Ripstop shell fabric, this winter coat is stuffed with premium 800-fill goose down to trap the heat. Quilted construction and small tight channels hold the down in place for precise insulation and also add a feminine flourish. Designed with a slim silhouette, this hooded down jacket is a versatile piece that will work as an outer layer on a summer bivy in the Sierras or as a mid layer under a shell when you're backcountry skiing in the Tahoe wilderness. The hood does not adjust but is contoured for a snug fit to maximize thermal efficiency. Two front pockets offer refuge for cold hands while a drawcord at the hem and elastic cuffs help seal in warmth. Tightly woven fabric helps block the wind and a DWR finish repels a few snowflakes or a light drizzle. Not just for adventures at home, the Mountain Hardwear Nitrous Hooded Jacket for women packs into a tiny parcel making it perfect for hiking trips in Chile and Nordic ski trips in the Alps.
