This rugged hard-shell beauty is perfect for pulling tricks at the park or just surviving the morning commute in style. With an intelligent cooling system that features eight air ports, your head stays breezy even when the action heats up. Braids and pigtails are no problem here, as the clever design is totally ponytail friendly for maximum comfort. Just give the handy adjustment wheel a quick spin to lock in a fit that feels like it was custom-made for your noggin.
