If you get into any type of accident it’s important to replace your helmet–even if it looks okay. However, if you have not been involved in a crash, most manufacturers recommend you replace your helmet every 4-5 years. While they are durable, the older they get the less safe they may be. Make sure to keep track of how long you have had so you know when to replace it. If anyone borrows it and gets into an accident, even if it is minor, you will want to replace it so you can make sure you are getting the best protection.
