I finally got myself a fullface helmet after a loooong market search. It seems that if someone has a large head then he is in big trouble with helmets. After trying Giro, Bell, 661, TLD i lost all hope since all where small. Luckily only Fox makes an XXL helmet 63-64cm and it fitted me like a glove. The helmet weighs approx 1400-1450g but it is MX-Race certified so it offers loads of protection. The build quality is next only to TLD, imho better than 661 and Giro. Only 3 vents though due to the MX nature of the helmet.
Here is a pic. I highly recommend the helmet to anyone in search for a supersized helmet.
PS the pic makes the lid seem larger than normal. Thats the lens of my cameraphone that are to blame for.
