Using this helmet is a breeze. Just put it on your head and use the Roc Loc Sport MIPS system to adjust the fit with one hand by turning the dial until it feels comfortable. When riding, make sure the helmet is securely fastened. As for maintenance, you can remove the quick - dry padding and wash it gently with mild soap and water. Let it air - dry completely before putting it back in the helmet. Keep the helmet away from direct sunlight for long periods to prevent damage to the matte white finish. And always check the helmet for any signs of cracks or damage before each ride.
