FIT/ COMFORT.

Besides that you are paying for color, name, "fashion", B.S. .

It used to be Bell was THE helmet to have in any sport, especially motorcycle helmets. Now they sell to WalMart and that has cheapened the name. But from what I see those helmets are as good as any. The more expensive ones may have better closures, adjustments and straps. But the basic protection is pretty much the same. Get something that fits and that you like.
