It's time to get excited about trapezoids. Turns out, this funky ol’ shape is ideal for helping sleeping bag baffles retain heat, especially when stuffed with 550 fill down. The trapezoidal baffle construction improves on Kelty's best-selling Cosmic 20 sleeping bag—and it’s just one of the reasons the Cosmic Down 20 is still a three-season workhorse.

Add to all this trapezoid talk a bevy of features, from a zippered internal stash pocket to an anti-snag zipper below the draft tube to a durable 20D nylong shell. You'll also love the natural-fit foot box for happier feet, and a PFC-free water-repellent coating for a healthier environment and heat-retention when moisture creeps onto the scene.
