We have long been fans Nutcase, but mainly because of the styles. In this new model, the same mechanism is processed by the seat optimally adapt as the children's helmets. I like the well, he actually slipped significantly less. The magnetic lock is a practical improvement for Erstgenerationshelm. Otherwise it is just a kind of skater helmet, not a very strong ventilation, which I have not missed in normal use. He sits like all skater helmets I know if you do not lock the tightening is not quite as stable on the head like a conventional bicycle helmets, which is significantly better through the adjustment wheel. The main advantage, however, is that the children here put this on the contrary to conventional Fahheadhelmen.
