What do you guys carry as a means to stay warm and dry for a night or two if you get stuck somewhere innawoods?

Say for backwoods day-sports like mountain bike riding where you only have a day pack or hydration pack. What should I have in case I get stuck?
Is pic related gud?

Had a scary experience recently where my bike failed and couldn't be repaired. It was getting dark and I was a long walk back to the truck. My buddies rode off to get the truck and I waited on a service road. It started to rain. They weren't back for an hour, by which time I was wet and miserable but otherwise fine. I was thinking that if something happened to them, then I'd be fucked.
