Most helmet manufacturers recommend replacing your helmet after 5 years. With normal use, the padding and harness can become weakened and compromised. Often the helmets are updated with new features and materials to improve safety and comfort. A helmet should always be replaced after an impact. Although it may appear intact, the inner protection could be damaged. All helmet companies offer some type of crash replacement policy. Check with us for further instructions. Several of our sales crew members are professionally certified helmet fitters.
