I got a chance to checkout Akuma's all-new Phantom II carbon fiber helmet, with a photochromatic visor. This thing is really cool! Unfortunately, I sold it before I could video it, but it went from clear to a dark smoke tint in 10 seconds.

While the visor is cool as hell, the helmet is really nice too. It is a "FULL" carbon fiber helmet, unlike the carbon overlay helmets out there. It weighs only 2.6lbs and is NICE!

Here are the details:
