When camping in the cold, we need multiple layers that aren't too bulky and provide an impressive warmth-to-weight ratio. One of our favorite mid or exterior layers is the Cotopaxi Fuego Down Pants. These down pants are stuffed with 800-fill power RDS-certified down and provide an impressive amount of warmth for their lightweight construction. The Fuego Down Pats are packable into their pocket for space-saving and have quarter-length leg zips for an easy on and off. The waistband has an elastic drawcord for an easy and secure fit, and two zippered hand pockets give us a place to stuff our hands when the weather gets nasty. The Fuego pants are made with a 20D ripstop nylon fabric and feature a DWR water-resistant treatments to shed any moisture.
