Title: Dual purpose liner
Review: I used this liner on a recent camping trip from the Arizona desert right up to Glacier National Park and found it excellent at both extremes. In the heat it was fine on its own. In the mountains it provided the extra warmth inside my mummy sleeping bag - we awoke to heavy frost on our tent several mornings. It has a full length zip and a stuff sack. I used it inside out so that the zip was on the same side as my sleeping bag zip.
