The streamlined design of the Fuego Down Vest is what keeps us going back to it on those unpredictable and in-between type days of weather. Cotopaxi has been updating it season after season to make it even more comfortable and effective. It has a slimmer, sleek design to sit close to our body, elastic armholes to close in the heat of the highly warm 800-fill down, and a light yet strong nylon face fabric for many seasons of adventure.
