Kelty Cosmic 550 Fill Down 0 Degree

Built to Keep you Cozy | Remember the trapezoid from 10th-grade geometry? Turns out, this funky old shape is ideal for helping sleeping bag baffles retain heat. The trapezoidal baffle construction improves on our best-selling Cosmic sleeping bag and it's just one of the reasons Cosmic 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.
