Kelty Cosmic Ultra 0 Degrees 800 DriDown Sleeping Bag (Regular)

Kelty have taken their top-selling Cosmic Ultra Bag and added a 800 fill DriDown version, with all the perks, to keep you toasty down to -8.0°C.

The new trapezoidal baffle construction 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.
