i have the Akuma phantom II helmet, its the lightest helmet i ever felt, and when i smashed into that suv head 1st, the helmet saved my life. the vents and visor smashed off the helmet but it did its job.
the best part of the helmet is how light it is the 2nd is the photochromic visor it came with. it tints in sunlight and stay clear at night or though tunnels and other dark areas...

here is my smashed helmet
i sent this picture to akuma told them how it worked for me and they sold me a 2nd helmet for $200 bucks (half off)
i want to try the carbon fiber bell star with the photochromic visor but at almost $700 plus $120 for the visor the akuma is a much better deal
