I'm thinking about trying a bivy with a tarp to get lighter. My limited bivy experience is with the US Army Goretex MSS Bivy, which I am not fond of, as it was a sweat bag.
I see all types of bivies out there - bug bivies, bivies with all manner of zippers and vents, hooped bivies, bivies with mesh and without mesh, bivies with a cord to attach to a ridge line to hold the "hood" up. I am in the SE and have to deal with bugs, rain, cold, hot and high humidity.
My main questions - is there a 3 season bivy, and if so, what does it look like?
OR do I need a bug bivy for summer and something else for fall/spring?
Can a side sleeper use a bivy or are they for the back folks only?
How do you keep it from having a condensation issue if it's all zipped-up?
Right now, I'm thinking I want -
Waterproof bottom, breathable top, mesh on the face, chest zip & side zip, cord to hold it off my face, and maybe a foot vent.
Thanks for all the advice in advance!
