    Absolutely love this helmet, especially paired with 509 goggles for perfect fitment. the "Hi-Flow" just means that there's extra vents, but these vents can be opened and closed to help keep you cool as well as dry out any moisture. Fid-lock should be mandatory on all helmets in my opinion, you'll never catch me riding without my chin strap done up again!
