Cosmic 0

Used the Cosmic 20 during a backpack archery elk hunt and loved the light weight and the warmth it had. Decided on getting the Cosmic 0 for an upcoming backpack mule deer hunt above 9000? in October. Early snow storm came in and luckily I ordered a second Cosmic 0 just in time for my dad. Temps in the morning were 5 degrees and the Cosmic 0?s not only kept us alive but I was warm and slept well with my layers and the bag. Sleek design, cozy and warm. Can?t ask for much else. Been using Kelty tents and backpacks for 20 years and I will continue to use them for the next 20+ years. For a little over $200 I find the Cosmic 0 tough to beat. Down hunting bags run about $6-700 nowadays and that?s not only ridiculous but not needed. Kelty all the way.

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 trapezoidal baffle construction improves on our best-selling Cosmic sleeping bag-and it's just one of the reasons the Kelty Cosmic Down 0 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.
