Caberg are very popular helmets over here in the UK. I've now had 2 Caberg flip front helmets and apart from wind noise, which is an issue with all flip front helmets, They were good and worked well with glasses. As with a lot of designs, the chin bar is very close to your face. My last one, a Justissimo, saved my face in an accident when the chin piece hit the roof line of a car at about 50mph. After the accident there were little cracks in the chin bar but it had stayed down and I just had a cut lip.
This time I've gone for a flip front helmet by Givi as it seems to have a bit more clearance to my kisser!
