I carry mine, when I need to, in a laptop sleeve inside my Timbuk2
bag, the big one (DeeDog). , waterproof as you care (stuff stays dry
in England. 'nuff said)
fits me fine; anything bigger would have been too big, anything
smaller would have been uncomfortably small--this size slings across
my back easily.

I am however a lot wider than the rest of the bikie population.
