Classic, best-selling down bag with redesigned baffles for extra warmth
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 the best-selling Cosmic 20 sleeping bag—and it’s just one of the reasons the Kelty Cosmic Down 20 is still a favorite three-season superstar. You'll also love the natural-fit foot box for happier feet, and a PFC-free water-repellent coating for a healthier environment.
