Have decided after reviewing the Amazon comments for this helmet. My buying criteria: no headache and becoming. Has confirmed everything. The helmet also looks after four weeks despite the white paint clean off. The field of view is, if at all, only limited upward. Small drawback: jackets with high collar can turn the wheel that hides behind under the helmet. The wheel then rotates so that the size will be adjusted to the head. Another drawback: The chin strap can be solved in the long term. Its construction has to be thought through a little. But it is when you know it, be set up, so that the belt holds.
