RAVEN..
like most bits of gear it's made to fit the needs and
abilities of those who chose to use it..the New Zealand Army
used the thermettes widely in WW II...Irish fisherman were
using their version at the turn of the century..in a sitution
where there was no fuel to be spared or had, it would be worth
it's weight in gold,,well maybe silver--anyway..there are
thermettes made of tin that are lighter..and--not every bit
of gear made for survival needs to fit in a band-aid box with
10 other things..i don't have a BOB..i don't think i'll ever
need one,but if i lived someplace where i had to get in my car
and try to get away from a disaster of some sort i would want
one of these in my trunk along with the canned food and tent.
but then again you have seen my honking huge packs---
