i think it have to do with the shape of the helmet as well. I felt that Bell are more "round" on the Skull area while HJC is abit more oblong... the proper sizing will depends on the shape of your head matching to the shape of the helmet. Thus some people can never get the proper fitting in certain brand. Best is test few brands until the perfect match is found.
