bruce z..i sure wish someone would come up with a pocket container that you can boil water in.the last good kit was by that mountain rescue group who used a old fashion tire patch kit box.flat and easy to carry in a jacket pocket and had the basic gear for a overnight shelter and hot drink.all the survival sites are full of "make do's" that are the wrong shape or too heavy.
except for the gear in my PFD i'll have to admit i don't carry a real pocket kit anymore,just a few things in my pockets.
