Warranty
Knock helmets are warranted against defects in materials and workmanship for two years from the date of purchase. This warranty applies to the original purchaser only and requires proof of purchase. The warranty does not cover damage caused by impact, accident, misuse, normal wear and tear, or modification.

Important: Any helmet that has been involved in a significant impact should be retired and replaced, even if no visible damage is apparent. EPP foam may be compromised  after a hard impact in a way that is not visible externally. If your helmet takes a significant impact within 3 years of purchase, contact us to receive 50% off a new helmet.
