My wife has a thing for handbags, so seeing as she is now a full blown everyday two child-hauling cyclist, I recently bought her the Barney Rustle. Smart move.
Originally from Melbourne Australia, it's a quirky brand, but these are fantastic bags - pretty much waterproof, convenient, comfortable, hold heaps and even look alright. I can see why messengers love these things. Bummer really though, because I was kind of hoping she wouldn't like it...
