I tried on helmets at REI today and the salesman said he wasn't comfortable with how high the helmets were sitting on my head. Too much forehead exposed, too high over my ears and too much of the base of my skull. He measured me at 57-58cm around, so not even an XL sized helmetz but apparently I've got a cone head, pushing helmets unsafely high. Any body else suffer from this? Have you found a helmet with interior space allowing it to sit lower?
