    Comments about Kelty Cosmic 20F Down Bag - Regular Size:

    I used this on an overnighter on San Gorgonio (11,500ft). The winds were gusting all night and I was quite warm. I only had the zipper zipped up about 1/3 of the way and had my upper body exposed. No problem. I can't imagine how cold it must be before I would zip it all the way and use the draw strings.
    I normally sleep warm.

    Other gear used was a FeatherLite mattress and a Eureka Solitaire tent (all purchased from SunnySports). I had no problem stuffing it back into the stuff sack that came with it.

    Would I recommend it to a friend? Yes. In fact I did.

    Note: This is not Goose Down. I believe I read it is DUCK Down.

    ALSO Note: I did not give 5 stars only because I have not had the opportunity to use it in near 20 degree temps.
