So anyway, don't look for a bike helmet company to repeat the mistake of offering an all weather helmet system anytime soon.
Well, paint me green and call me Kermit.
Giro is offering the Timberwolf and Shackleton 'winter' helmets.
And Specialized is offering the Centro Winter (plus the regular Centro and a separate winter inner insert).
The Centro can fit a purpose built LED tail lamp as well.
These still lack the fitted, snap on rain cover the old Bell Metropolis had, but a slip over cover can be added aftermarket from numerous sources.
