Get Schooled in the Geometry of Comfort
The Kelty Cosmic Ultra 0 is the ultimate in a lightweight mummy. We've taken our top-selling Cosmic Bag and added an 800 fill DriDown version, with all the perks too. The new trapezoidal baffle construction improves is ideal for retaining heat-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.
