Thanks for all the suggestions! The Marmot Helium and Marmot Hydrogen are 15 and 30 degree F bags with weights of 2 lbs 6 oz and 1 lb 12 oz, respectively. Probably I could get by with a 30 degree F bag, but it is easier for me to get cooler in a bag than it is for me to get warmer (if that makes sense? I control my temp by sticking one or both feet out into the cool air. Then I am happy.) so I would rather have the extra 3 oz with the WM ultralight. So sorry Pika, but the Marmot's are out of the running (although the $300 price tag is very nice for the quality...the other 2 are basically $400).

The other consideration is that I will have to wait a month for Feathered Friends to produce more hummingbird nano longs. Its looking more and more like a coin toss...ALTHOUGH, first I will check and recheck the measurements.

Ya know, I would have responded yesterday evening but I couldn't get the web site to respond. Its much better this morning.
