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.

　　What makes it a women’s bag? It’s designed for and tested to women’s specific ISO standards. Studies show that women “sleep colder” than men. So, in addition to narrower shoulders, wider hips and a shorter torso, Kelty women’s bags have extra insulation in the upper body and footbox.
