Does anyone else use these things as a stand-in for a sleeping bag? I carry a lightweight fleece blanket too, which hardly ways anything, and I am very warm even in winter if I sleep in my coat. It makes me wonder why I kept carrying that cumbersome and much heavier bag around when it would hardly ever fit in my bag. With the McCandless blanket you can save weight and a lot of space.
I don't think they work that way.
>>2846374I've used them to "sleep" during Search and Rescue overnight exercises. Sleep is a very, very generous term here. More like lay on the ground and shiver and daydream of your warm bed and how many more hours it'll be before you can get up and start walking because walking will warm you. >>2846382 is right. They don't work the way that you think. The best advice I was given is that these are better than freezing to death. That's a good way to describe them. You aren't going to freeze to death, but you aren't going to sleep and camp with this thing. Look into a bivy. They're cheap these days.
>>2846374Lol if that blanket is keeping you warm then it isn't that cold out
