Size Chart for the HCI-75 Carbon Fiber Sportbike Helmet DOT
Please use a cloth tape to take your measurement. It is better to have a helper do the measuring in order to get a more accurate measurement.
The circumference of the head should be measured at a point approximately one inch above the eyebrows, or at whatever point gives the largest possible measurement.
If you find that your measurement falls between two sizes, choose the smaller size.
Comment: This carbon fiber helmet is very lightweight is of excellent construction. It rivals thosecosting three times it's price. This is a great buy.
