Cut no corners when protecting your head. Get a helmet that fits snugly (but not headache-tight) and has been approved by the Hockey Equipment Certification Council, the Boston-based organization that has set the standard for safety since 1978.
Versatile fit is the main attraction of the Bauer 8000 ($120). The helmet comes with three sets of adjustment straps, making it easy to fit it to any head. The two-piece design of the CCM Tacks 852 ($75) allows for some adjustability, but its main selling point is good protection with maximum ventilation. For an extra $50, add the Oakley Visor, a distortion-free face shield.
