The helmet functions well and is very comfortable and pleased with my purchase.
I would however recommend not buying it with the mask. As blake posted in an earlier review "The only problem I had with the setup was the mask. The horizontal bars affect my visibility", I can't agree more. I was using an older helmet with a true vision visor and find this mask sits too close the the face and blocks my vision badly.
Only other minor thing I don't like about it is the fact that there are slots in the forehead padding. This causes sweat to run down the face rather than my previous helmet that had a solid peace which moved the sweat down to the side of the face, keeping it out of your eyes.
