Marca and I decided to get the same helmets some time ago. We liked the grey color, so started with that, liked the HJC so added that to the list. Went to our local dealer and tried on the two they had, mediums were the choice. Hers fit right, mine didn't. We exchanged the units with each other and now neither was comfortable. Went to another dealer who had 4 of the right choice. One fit right, the others didn't. They said: no problem, come back next week and we will have 4 more for you to try. We did and they did. So all the helmets were HJC medium, silver color, 3\4s. Out of 12 'identical' helmets we found two to be comfortable, but hers is not comfortable for me or vice versa. I find it interesting how those thingies all come out of the same mold but are all different somehow.
