Warm and cloudless nights don't require shelter, but having the Kelty Cosmic 40-Degree Down Sleeping Bag is quite nice when you're sleeping under the desert stars. Its 600-fill DriDown will stay warm even if it gets a little damp, so dew won't wake you up before you're ready, and the soft taffeta lining will help you stay comfy even if you decide to sleep in the buff. Kelty also decked the Cosmic out with a Thermal-Comfort hood, draft tube, and Natural Fit footbox, so you'll stay warm even if the evening is a little bit breezier than anticipated.
I find it very annoying how inconsistently sleeping bag temperature ratings are advertised. I tried to be as thorough as possible, looking this bag up on multiple sites to get a good idea of the comfort rating, it said 40 degrees across the board. Then it arrives and the tag says 40 degrees for MEN, 50 degrees for women. I probably should have known...but it also probably should have been advertised. Anyway, I have now used this on multiple backpacking trips over the summer where it tends to get down to 55-60 degrees at night and I have been chilly but it was okay. Then I got a bag liner and it was a perfect temperature. It is at least a lightweight bag so I can definitely recommend it for summer hiking but I recommend a liner, more so for women
An amazing update to this Best-Selling bag. It's lighter, softer, and more compressible than ever. All for a full down bag that is STILL well under $200.
