Remember the trapezoid from 10th-grade geometry? Turns out, this funky ol’ shape is ideal for helping sleeping bag baffles retain heat. The trapezoidal baffle construction improves on our best-selling Cosmic 20 sleeping bag—and it’s just one of the reasons the Kelty Cosmic Down 20 is still our favorite three-season superstar. We also love the natural-fit foot box for happier feet, and a PFC-free water-repellent coating for a healthier environment.
Features • Innovative trapezoidal baffle construction = thermal efficiency • Lightweight and warm 550 fill down • Environmental and health friendly C0 and PFC-free DWR fabrics • Zippered internal stash pocket for headlamp, cell phone or actual… stash • Buttery-soft and durable 20D Nylon shell fabric • Zipper draft tube with anti-snag zipper design makes it easy to get in and out • Dual slider for ventilation with locking zippers • Natural fit spacious footbox = more room to wiggle your toes • Comes with stuff sack for quick departures.
