>>2504157I live in an uninsulated van, use a - 10C rated bag. Got down to -8C last night and it was fine, and I'm a skinny bitch.
Just wear your layers to bed and make sure you're all in your bag. Also have some tea or something before bed. And use a pad so you're not right on the ground.
Honestly mornings are the worst part. Going to sleep you're still warm from the day and moving around, getting out of your nice warm pouch is Hell on Earth.
