Are you right! It is NOT spring yet. We just got a good snowstorm in the mountains- chain controls on passes. But, we are THANKFUL- so far it has been big-time drought in the Sierra.

I am a cold sleeper, and have never regretted over-kill on my sleeping bag. I carry a 10-degree bag EVERYWHERE! I definitely pare down me clothing but feel the weight of a sleeping bag is really the most efficient warmth you carry in your pack. When I win the lottery, I will buy a sleeping bag for every 10-degree temperature rating! For now, I have to do with one bag to cover all kinds of conditions. I would recommend that unless there is a compelling reason that you want to reduce about a one pound of weight, I would err on the side of a beefier sleeping bag.
