Get Schooled in the Geometry of Comfort
Remember the trapezoid from 10th-grade geometry? Turns out, this funky ol’ shape is ideal for helping sleeping bag baffles retain heat. The women’s specific Cosmic features trapezoidal baffle construction for increased thermal efficiency—and it’s just one of the reasons the Kelty Women's 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.
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, our women’s bags have extra insulation in the upper body and footbox.
