Santa's little helpers

are the space blankets good? In the mountains we didn't rate them at all, better to have a bivvy bag, which traps air which can then warm up, not a criticism, earnest enquiry, have you seen homeless peeps with them?

I'm not sure that space blankets would be the best option as I don't think they're breathable and noisy. If someone is out in an exposed location then being damp, even inside a cover can exacerbate health problems. Might be better to get a load of fleece type blankets. They're more susceptible to getting wet but if used in a sheltered location will still breath and they dry out pretty quickly and are easier to launder when the get soiled. Bivvy bags can have similar problems to space blankets if used over the long term.
