To use the Gilbert XP500 body armor, simply put it on like a regular shirt before your rugby match or training session. It's designed to fit snugly, so it'll support your muscles as you play. When it comes to care, hand wash it in warm, soapy water. After washing, hang it to dry - don't use a tumble dryer. Also, avoid using bleach, ironing, or dry - cleaning it. This way, your armor will stay in great shape for many games to come.
