This may sound very basio, but do they come in more than one size? I purchased a damaged one several years ago I just finished repairing and, while the label is intact and makes no reference to size, the protector wouldn't fit in a medium GS Mk 6 helmet, but fit nicely in a large/oversize. From this I'm assuming they were made in multiple sizes, but how do you know which one you have?
