It has happened to me a couple of times that I have shelter and plenty of insulation underneath, but my 1-season sleeping bag turns out insufficient for the spring snow that surprised me at nightfall. What should be done in such conditions?
I have tried:
- Enabling alarm every 30min or one hour in order to prevent white death
- Zipping the bag all the way, only my nose protruding. Unfortunately below freezing temperature breathing the icy air is very very uncomfortable.
- Zipping the sleeping bag and forming a ball inside. Unfortunately everything turns wet by the morning and even before that.
Heck, how do people in quality sleeping bags sleep in the winter with all that sub-zero air that they have to breath?
