I have a rei quarterdome or something like that tent and it works real good. It comes in at just under 4 pounds. I kinda wanna shave a little weight off pack though. The bivy idea looks essentially the same as tent, just lighter and obviously less room. The other option would be hammock. I keep hearing and reading about hennesy hammocks but, I am a shitty sleeper even in a bed and i must lay on my sides. I have always thought of hammocks as a lay on your back kind of thing. I usually go camping/backpacking in the Olympics but occasionally go out to the desert seeing that i go to wsu. What are your guy's opinions and experiences in terms of bivy's and hammocks?
