Good warm weather bag

Comments about Kelty Cosmic 40 Degree Down Sleeping Bag:

I had this out on the Appalachian Trail a few days ago. Temps never got below 70 at night so I can't comment on how warm it would keep you. It served as a decent cushion over top of my sleeping pad. Quality seems good. The weight and pack size is excellent. Packs down very small with included sack and if put in a true compression sack, would pack even smaller. For the price, weight, and pack size- I don't think you can find a mud better deal.

        Comments about Kelty Cosmic 40 Degree Down Sleeping Bag:

        Super portable and lightweight, good for summer/spring. Used it on a recent bareboat sailing trip and was very happy. This packs down to about the size of a football, but much lighter. Not for a tall person, however, and a little narrow at the feet, but didn't impact my sleep. Get this if you want to go really light, and on cooler nights don't mind adding a layer of clothing when you sleep.
