I bought this bag right about 1 year ago. I was headed out on a cross country bike ride in June and I wanted something that would get me through the cold June nights at higher altitudes we might run into, but not be too heavy. Well, this bag worked great. It always seemed to keep me warm, even the dreaded night of the sprinklers. We were sleeping in a baseball dugout in Wyoming and at midnight we wake up and we're already soaked because the sprinklers had turned on. By the time my friend figured to put the trash can on top of the sprinkler our stuff was thoroughly soaked. However I slept through the rest of the night wet but warm, while my two friends froze their butts off and had to take naps at 6am when the sun came up. I recommend a compression sack if you want it to be small.
