The helmet is really easy. Unfortunately, he also has weaknesses that one finds only in use. Firstly, it is quite wide, caused probably by only 2 variables. With a head size of just 60cm (helmet goes from 58-63), he does not sit firmly as he wobbles, even when adjusting the Regulierband. On the other hand while driving, if you do not just sit and Hollandrad, and you're wearing a jacket, then the helmet moves forward and you have him constantly pushing back, is just annoying. The problem is because the helmet is pulled back deep and is pushed up by the jacket collar. Prima I find the light behind the helmet and the air vents, which can also be closed. The helmet does not look like the athletic sports cyclists and that should it indeed probably not, at least not for normal recreational riders.
