The fit of the helmet is great out of the box, sitting correctly on both my 12 & 13 year old girls. We only needed to set the chin strap properly, certainly one of the best fitting helmets Ive had. They really like the skate-style of the shell vs a traditional bike helmet design. BUT they strongly disliked the graphics, so much so that they picked this helmet only when others were not available & I insisted they wear one. If youre not wearing a helmet it cant protect you, and if you dislike the graphics so much you wont put it onwell thats a big miss by the manufacturer.
