"What Our Gearhead® Experts Are Saying:""This jacket blends classic style with modern performance. The ultralight design keeps me warm without adding weight, and I love that it packs into its own pocket—perfect for tossing in my pack on winter hikes or travels.""The Marmot Ares Down Jacket delivers everything we need for lightweight warmth, whether we’re hitting the trail or heading into town. Built with retro-inspired style, this jacket combines 600-fill down insulation and a DWR-treated ripstop shell to fend off cold temperatures and light moisture. We stay cozy while the ultralight construction keeps bulk to a minimum, making it perfect for layering or stashing in a pack when the day warms up. Designed for movement, the Ares Jacket’s Angel-Wing Movement™ ensures unrestricted comfort, while an elastic drawcord hem and zippered hand pockets add thoughtful functionality. When space is limited, it packs neatly into its own pocket, so we’re always ready for spontaneous adventures or chilly commutes."
