If your looking for the specific helmet depicted in the photo you provided its actually the Pro-tec Ace Pro helmet:

You can tell its the Ace Pro version because it has 4 oblong vent holes in the front instead of the 2 circular holes in the Classic version. You can pick it up at Sportmart for about $50.
