Using your CORE Action Sports Helmet is easy. First, adjust the chin straps to fit your head size comfortably. The red safety buckle makes it simple to fasten and unfasten. When you're out skating or cycling, make sure the helmet sits firmly on your head. As for maintenance, remove the inner padding every so often. It's removable and washable, so you can keep it fresh and clean. Store your helmet in a cool, dry place. Avoid exposing it to extreme heat or sharp objects that could damage the outer shell. If the helmet has been in a significant impact, it's best to replace it for your safety. Check the safety certificate regularly to ensure it's up - to - date and valid.
