Using this neck collar is easy. Just put it on around your neck and fasten the Velcro strap securely. Make sure the rear helmet support fits well against your helmet. When it comes to cleaning, simply unzip the collar, remove the padding, and throw both the outer cover and padding into the washing machine. After washing, let them dry completely before putting it back together. As for maintenance, check the Velcro regularly to ensure it still sticks well. Avoid using harsh chemicals on the collar as it may damage the material. Also, store it in a dry place when not in use to keep it in good condition.
