Some years ago, Bell offered their 'Metropolis' model. It wasn't just a bike helmet, it was a bike helmet system with an available snap on rain cover, a visor, a mirror and a winter insulation kit including ear muffs. Cyclists reacted like they were being offered chicken pox, and retailers closed inventory of these out at deep discounts over the next several years. Don't expect Bell or another helmet manufacturer to offer anything like this again anytime soon.

I've got one with all the optional stuff, purchased about forty cents on the dollar. It's a good helmet and all the accessories work well. Yeah, I generally only wear it in the cold or when it's raining. I'm not sure what I'd replace it with.
