I really like the look of my Wife's
Bern Brighton in Gloss Purple. As far as aesthetically pleasing it does it in a nice classic style that doesn't look out of place on a C&V bike or a modern bicycle.
There are a number of modern helmets that don't look too unappealing visually. I think what I like about the Brighton (other than the purple color because I really dig purple) is the built in visor cap with the liner. The visor really makes that helmet and gives it a touch of being a hat and not so much a spaceman spiff look of many modern helmets that just turns me off aesthetically. My wife just bought this helmet at the end of last year's riding season to replace a helmet so old it could rightly claim credit to C&R status in and of itself. It was the older brainpan shaped softshell beer cooler with the fabric cover. My wife really wanted the impact protection of a helmet in case of a spill and I was dubious as to the ultimate efficacy of that old POS helmet as well as the negative neck-twisting effects of the helmet sliding along on the pavement wearing such an ancient fabric-covered monstrosity.
I like the Styling of that Bern and will probably be soon buying one for myself as my current helmet is falling apart from the sweat and will need replacing sooner or later. I like the Macon and Brentwood styles -I'll probably wait and see if one goes on sale/clearance this fall.
