Bontrager Helmet Women

1. How to measure your size

Wrap a measuring tape around your head, keeping the tape level from front to back. Note the measurement and use the size chart as a guide. If you are not sure about the measurement, ask your retailer for assistance.

2. How to adjust the fit

Step 1: Adjust the fit system at the rear of the helmet for a snug, secure fit. Some helmets also include a vertical tuning feature that allows you to adjust the fore/aft tilt, for optimal positioning on your head.

Step 2: Adjust the straps so that they sit just below the earlobes.

Step 3: Adjust the buckle so that it rests against the back of the jaw/throat.

Step 4: Adjust the interior pads if needed.

Step 5: Check the fit to make sure helmet is comfortable and secure. It should not roll forward or back, or be able to slide off.
