Thanks for all the info in this thread - I'm also looking for a messenger bag and am a southpaw. I'll waht size suits when I try it on, but can't really mail -order one

Near as I can tell, the Timbuk2 bags are symmetrical, so can theoretically be worn over either shoulder. The Citizen bags are 'handed'.

Oh is that Crumpler bag from T9 waterproof? I can't find anything on it.

cheers
