Grex Flip front
 

I used this helmet for the last 6 months...its plastic, cheap 80Euro...but really pretty crappy..very noisy and the clips get clogged and stuck with bugs, dirt etc...Ok.. so the chin bar should be down when you are riding, I have a small scar to prove it. Basically if you can afford better ..do iT. Unfortunately nobody stole it.
