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 secure. Put the helmet on and make sure it sits comfortably on your head. When you're out skateboarding or cycling, the 11 air vents will keep your head cool. After using the helmet, you can remove the 3 pieces of inner padding and wash them to keep the helmet fresh. Store the helmet in a cool, dry place. Always check the helmet for any signs of damage before each use. If it's been in a serious impact, replace it for your safety. This helmet is designed for action sports, so don't use it for other purposes.
