Those Tyvek tube tents are interesting but

I don't really like the ones with open ends except maybe summer, and skeeters and bugs would carry you off, maybe a snake for a buddy too. Many are Mylar too. Very thin plastic but it does reflect heat. Small and light, most are $10 or less.

I like this one with closed ends for winter (lost in the woods). I think it is Tyvek with Mylar lining. A guy tested one in 30 deg. and in a couple hours his body temp rose it to 60 deg. It was drawing surface moisture though. But to keep you alive it's probably good. You do need a couple trees or posts to set it up.

This is getting close to a cheap pup tent in price. Probably one of those pocket Mylar rigs would be more economical for something you really do not intend to use. But for a bug out I kind of like this. It's about small notebook size and 1.5 lbs.
