Thanks for the replies. I thought I filled out my location info.
I'm in Texas! Just North of Austin.... so, no I'm not getting snow much nor sleep in it...yet. But, since I was cold...and I like being prepared, I figured I would get something warm. I have read on other forums to take about 20 off a rating, and I was thinking that if it was too warm, I could also open it up and vent. So a 0 degree is good, maybe a -15 would work also. Next week I am driving up to Kansas and Colorado, I wouldn't mind having a warm bag just in case...
I too read about slumberjack and read some reviews on 1 or two. I saw a lot of praise on the Backend and since it is around $100 I am still considering it as well. It is synethetic and I like that if it does get wet, it will still be warm. I too am 6'4" and need a larger bag. The bags I mentioned are all long bags and have a good width as well.
As someone mentioned, I think our air mattress didn't help us stay warm, although it has a velvety top, it did have all that cold air in it. Also, we did luckily have an extra sleeping bag, although it was a summer bag.
Thanks for the suggestions. GTeagle
