To begin, it is immediately noticeable that the inner padding is made from soft beige rubber foam. But look closer; the front rivets holding the padding in place are absent, with no sign of removal.
From my research, I have seen the beige padding peeking out around the edges of JOFA 366's worn by the pros, but until I found this helmet, I didn't take much notice. I was pleased to find that Mario Lemieux wore a helmet similar to this! Notice, though, in these pictures his ear loops are narrow plastic, even different from the standard JOFA 366; but you can see that the padding is the same, and that the rivets holding the front padding in place are absent.
