I'd like an urban helmet as well. Often I'd rather lock up my helmet than carry it around, but I'm hesitant to lock up a pricey and delicate one like the Giro Ionos I generally use. I would want something that's not too costly that I don't want to leave it somewhere locked to my bike, and that can take a few (non-crash) bumps without having to be retired, something like a hardshell skate helmet. Ventilation, weight and looks are issues though - has anyone tried the Uvex Urban? It looks almost perfect.
