For fast-and-light climbing missions, extended backpacking trips, or backcountry ski tours, the Marmot Mens Zeus Down Jacket gives you the warmth of a down jacket for less weight than a traditional fleece. 800-fill down insulation provides low-bulk warmth when you dont have space in your pack for a huge down layer. A wind flap behind the zipper eliminates drafts, and the jacket packs up into its own pocket when its time to climb.Product FeaturesMaterial: [Shell] downproof nylonInsulation: 800-Fill downHood: NoPockets: 2 HandWaterproof: NoCore Venting: NoRecommended Use: Climbing, skiing, backpackingManufacturer Warranty: LifetimeCountry of Origin: China
