All season universal half helmet detachable

How to correctly wear the motorcycle helmet: 1. Measure the head circumference or determine the size of the helmet after trying on the helmet. When wearing, open the rear adjuster to the maximum. 2. Wear the helmet horizontally and do not tilt forward or backward. The backward tilt of the helmet will block the vision and cannot protect the safety of the rear position of the head. The forward tilt of the helmet in motorcycle vehicle accessories will cause the helmet to fail to protect the safety of the forehead position. 3. Screw the adjuster tightly until the helmet does not shake and feels comfortable. 4. Adjust the height of the black split buckles of the webbing on both sides of the helmet of motorcycle vehicle accessories, so that the ear position is just between the front and rear webbing. 5. Adjust the length of the jaw socket and fasten it, leaving a finger gap in the jaw, which is a safe and appropriate wearing method.
