Using this Canterbury Raze LE Headguard is simple. Just put it on your head and fasten the chin strap. Make sure it fits snugly but not too tight. Remember, this headguard is not for preventing concussions. It's mainly to protect your scalp and ears from cuts and abrasions and help prevent cauliflower ear during rucking and scrumming. When it comes to maintenance, hand wash it in cold water. Don't use hot water as it might damage the materials. After washing, let it air dry. Avoid putting it in a dryer. By following these steps, you can keep your headguard in good condition and use it for a long time.
