The Heatsheets Bivvy and Blanket look great. These are the ones from Adventure Medical, yes? The price is right. Are they reasonably durable?

I wonder if a poncho made of this reflective material would be a great do-everything combination. It would probably get too hot for moving around in, but I think it might be very useful when just sitting around. I did a quick search and saw one on Amazon, but have no idea about the size or quality.

Any other recommendations appreciated!
