The versatile, lightweight Marmot Featherless Jacket will add a nice bit of warmth to all your cool weather outdoor pursuits. Whether you climbing, hiking, or out for a nice evening on the town, the 3M Thinsulate insulation will keep you comfortable. Thinsulate is comparable to down, but unlike down, it can retain its warmth when wet so surprise afternoon snow flurries won't dampen your adventure. Elastic cuffs and hem seal in your body heat for added warmth and when it's extra cold, the Featherless Jacket is Zippin compatible so it can be paired with select Marmot jackets for robust protection from the elements. At the end of your adventure, the space-saving jacket stuffs into its own pocket to reduce space in your pack for convenient transport back home.
