Using the Giro Fixture MIPS II Youth Helmet is easy. First, adjust the Roc Loc® Sport fit system to make sure the helmet fits snugly on your head. It should sit level on your forehead and not be too tight or too loose. When you're out cycling, whether it's on the road or off - road, the helmet will protect your head with its Mips® system. After your ride, if the padding gets dirty, you can remove it and hand - wash it with mild soap and water. Let it air - dry completely before putting it back in the helmet. Store the helmet in a cool, dry place away from direct sunlight. Avoid dropping or hitting the helmet hard, as this can damage its protective properties. Check the helmet regularly for any signs of wear and tear, and replace it if it has been involved in a crash or shows significant damage.
