It was important to buy a bicycle helmet, on the one hand, of course, provides the appropriate security, but at the same time easy to handle and in addition still looks good. After various test reports on the Internet, among other things, this helmet came into consideration. This helmet gave the impression to fulfill all the above points positive. So ordered, and after only two days apart (!). It was really really great, so I did not have to wait long for the helmet. Once home, he held the helm of what he promises. It can be very easily adjusted by a rotary knob mounted on the back of my head optimal size. On top of that is in the scroll wheel even an LED light integrated, which can be set as a flashing or steady light and is well seen just at dusk and darkness. The helmet is comfortable to wear. The many air holes, the head - even at higher temperatures - good "Ventilate" :-) Overall, in my view, highly recommended!
