You might have to look for a while.

Several years back Bell offered the Metropolis 'helmet system'. The Metropolis helmet could be fitted with optional visor, mirror, foam inserts to plug up the ventilation slots, ear muffs that slipped onto the straps and a snap on rain cover. There were attachments where you could clip little LED to-be-seen lights onto the front and rear. It was a helmet for riding at all hours in all seasons and all weathers.

It was universally panned on bike message boards and sold very poorly. It lasted a single year on the market. Charitably, this was not a money maker for Bell. I picked one up, with all the accessories, on deep discount closeout a year later. IMO it was a brilliant design and I'm still befuddled why it didn't find its niche in the world of cycling.

So anyway, don't look for a bike helmet company to repeat the mistake of offering an all weather helmet system anytime soon.
