The Fuego is Cotopaxi's quintessential down insulation layer. It's made with responsibly sourced, water-resistant 800-fill goose down, making it the lightweight down jacket they can't seem to take off from fall through spring-they even take it camping in the summer. This versatility comes courtesy of its toasty down insulation, breathable Polartec Alpha underarm panels, and DWR-finished ripstop nylon shell. Cotopaxi also added a built-in scuba hood and elastic binding throughout, further sealing out the cold, and the assortment of stash pockets throughout provide space for all your essentials.
