okay...arguments for both types of materials. While we are on the subject of bags can we recommend a bag that will work in Wyoming and Colorado during the months of September and October. Temperature ranges would be expected to be from 10 to 40 degrees. Sleeping bag would be used for backpacking and camping near my car. Will need to fit in my mystery ranch Metcalf with my tent and other stuff.


please recommend 1 bag in the
200,300,400 dollar price range.
