Using your CORE Action Sports Helmet is easy. First, adjust the chin straps to fit your head size. The red safety buckle makes it simple to fasten. Put the helmet on your head, ensuring it sits comfortably and the ear cut - outs align with your ears. When you're done riding, take it off carefully. For maintenance, you can remove the 3 pieces of inner padding and wash them regularly to keep the helmet fresh. Store the helmet in a cool, dry place. Make sure to check the helmet for any signs of damage before each use. If you notice any cracks or other issues, it's time to get a new one. And always remember, this helmet has an AUS/NZ safety certificate, so it's designed to keep you safe during your rides.
