for hypothermia on the east coast they use two space blankets , the

looks like your blizzard pack has that whole recipe covered. much less
space too.

Only real caveat is that they're vacuum packed and once they come out of
their wee baggie they don't really go back in it. The manufacturer does
offer a repacking service but that would probably be a bit of a pain
from Canada, but at least they're not one shot wonders. My pals that
have used one in anger (and been impressed with it) just carry it around
in a bigger-than-VHS cassette pack now.

Being basically waterproof, so the insulation doesn't degrade when wet,
is a rather huge bonus for paddling.
