I bought 8 years ago a cheap helmet, which cost then 5. Now I've seen a test on television while this helmet was next a very expensive helmet highlighted. When one considers the size of data, you can order the helmet also online. Head circumference measure and choose a size. Sits very well.
Improved I was with this helmet but not because he looks exactly the way as I had. I kept him anyway, I use the helmet with cap, the other without. Conclusion: security need not be expensive.
