Arai Corsair X

[Grumpy Goat]

Agreed, I use the V-Pro on my Signet-X as well. It's a great tool when riding the Blue Ridge Parkway with the tunnels. Makes for a quick change from sun to darkness. I've yet to use any photochromic eye wear that can change fast enough for those types of situations. Perhaps someday......

On entering the tunnel one can always flip up the visor for a few seconds while the photochromic visor adjusts. With photochromic glasses behind the photochromic visor, my glasses are light enough that flipping up the visor is the solution for me. Any helmet which offers a photochromic visor gets the topmost immediate advantage from me, compared with other helmets. Only downside to these visors is the expense.
