On my last outing, I had discovered that my 30 degree bag was not cutting it for top warmth (I also had an AHE jarbidge UQ but that worked great). Although it is currently summer, I frequently backpack/camp overnight in higher elevations where the temperatures may drop close to freezing (It is supposed to be 90 degrees today and I still can see some snow on the mountains!).
So I was considering my options on upgrading my sleeping bag to a down quilt. Seeing how I do not want to spend that kind of money, nor do I really have much time for a DIY top quilt, I have been considering what other options that I have...
I came across the SOL Emergency Bivvy, which weighs in at only 3.8 ounces and claims to reflect 90% of body heat. This might just be the perfect thing to add some extra insulation to my sleeping bag! I just have a few questions on those of you who may own/have used one of these on camping/backpacking trips.
Did you use it by itself or along with a bag/quilt? What kind of temps were you in? What temps would you think you would be comfortable with, in one of these bivys? Did it turn your bag into a sweat-box, trapping moisture? Any first hand experience/ input is appreciated!
