Bivvy.Also claustrophobic as all get out. The joy of light weight goes away fast the first time you have two days of non-stop rain.
Not free-standing, it just lies there.
No room for your stuff, just you.
Maybe add a sil-nylon tarp to the kit for extended canopy and to cover the gear you're not going to get into your bivvy.
Of course. That's why you have the tarp. Getting stuck in a two- or three-day storm is a risk we all face when touring completely self-supported. If you're gong to go nuts in bivvy with a surround of tarp-protected space,you will probably still go nuts in a tent, even a large tent. Have you ever read the journals of Everest and K2 climbers who share a tent with two to ten other people for five or six days, completely socked in by raging storms? Compared to that situation, a solo bivvy in a thunderstorm is paradise. It's all relative.
