Here's the official Reebock Recall:

December 4, 2008 (Montreal, QC) – On December 2, the Consumer Product Safety Commission released a recall notice, in the United States, on a number of RBK and CCM hockey helmets. The recall pertains to an issue that first came to our attention during the summer. In July, we alerted all affected retailers of the possibility they had received some helmets that did not fully comply with a relevant chin strap standard. We discovered in our internal testing that a helmet component that did not fully meet our internal quality control standards had made it into a small quantity of finished goods. We knew that the potentially affected helmets shipped from our distribution center between the limited period of June 1, 2008, and July 16, 2008. Therefore, we initially only contacted those retailers that received shipments during that period. At that time we asked the retailers that were possibly affected to check their inventory and return to us any helmets that matched the serial number pattern described in the recall notice. This process enabled us to retrieve and repair a large percentage of the affected helmets.

Any consumer that has a helmet described by the CPSC recall notice should return to the store where they purchased the helmet. If the store had not been contacted by Reebok-CCM over the summer, it means that they did not receive any of the potentially affected helmets. If the retailer was part of the initial recall effort over the summer and the helmet has a serial number that matches those described by the recall notice, the helmet will be replaced free of charge.

We apologize for any inconvenience this recall may cause. The safety of our customers is our highest priority. Should you have any questions or need assistance, please contact our Customer Service Department at 1-800-451-4600 if you are located in the USA, or 1-800-636-5895 if you are located in Canada.
