Bad set

Both the helmet itself as well as the helmet strap closure I have difficulty in finding the right attitude. If one helmet inner belt a eating too hard, 'jumping' the helmet after a certain time rises dramatically, this is not done, he sits at the outset too loose. It is similar with the chin strap, which runs just above the shutter Adam's apple, if it is to determine what is reasonably unpleasant, he otherwise but to loose.
