I had my doubts when I read here how many had struggled with the size. Have the items ordered in spite of everything and have to say that this was a real bargain. Helmet fits perfectly (with normal head size, have unfortunately only a ruler at hand, since the dimension could be somewhat inaccurate ;-)). If you set the Einstellradrad to a larger head circumference, fits securely even under it a thin cap. I personally attach much importance to the fact that I hate to stow all equipment for the break on a mountain pasture in the jacket and trouser pockets.
