The best way to put on the helmet is to hold the chin straps to each side before pulling it over your head. Pass the end of the strap through the D-rings and pull it snug. Keeping your head straight, rotate the helmet from side to side with your hands. If helmet is adjusted properly, you should feel the movement of your scalp closely match the helmet's movement. With your hands on the sides of the helmet, move the helmet in a slight up and down motion. Once again, the movement of your skin should follow the helmet movement. To remove the helmet, pull the D-ring tab outward to release strap tension, then unthread the chin strap. Pull the chin straps outward, rotate the helmet forward and lift it off.
