Operating Instructions
Familiarize yourself with the helmet's controls for optimal use during your ride.
- Main Visor Operation: The clear outer visor can be opened and closed by lifting or lowering it from the bottom edge. It has multiple detent positions to allow for partial opening.
- Sun Visor Operation: The internal sun visor is operated by a control switch located on the side of the helmet. Slide the switch forward to deploy the sun visor and backward to retract it. This allows for quick adaptation to changing light conditions.
- Quick Release Buckle: To fasten, insert the male end into the female receiver until it clicks. To unfasten, press the red button on the female receiver and pull the male end out. Ensure the strap is snug under your chin.
- Ventilation System: The helmet features adjustable vents on the mouth guard and top of the helmet. Slide the vent covers to open or close them, controlling airflow for comfort and fog prevention.

Maintenance
Proper maintenance extends the life of your helmet and ensures its continued protective function.
- Cleaning the Shell: Use a soft cloth, mild soap, and lukewarm water to clean the exterior. Avoid harsh chemicals, solvents, or abrasive cleaners, as these can damage the shell material and finish.
- Cleaning Visors: Both the clear and sun visors should be cleaned with a soft, damp cloth and mild soap. Rinse thoroughly with clean water and air dry. Do not use abrasive materials or chemical cleaners, which can scratch or damage the visor coatings.
- Cleaning Padding: The removable interior padding can be hand-washed with mild soap and water. Allow it to air dry completely before reinserting into the helmet.
- Storage: Store your helmet in a cool, dry place away from direct sunlight and extreme temperatures. Use the provided helmet bag to protect it from scratches and dust.
Troubleshooting
Here are solutions to common issues you might encounter:
- Excessive Wind Noise: Ensure all vents are closed if you desire less airflow. Check that the main visor is fully closed and sealed. An improper fit can also contribute to wind noise; verify your helmet size.
- Visor Not Sealing Properly: Inspect the visor mechanism for any debris or damage. Ensure the visor is correctly seated in its pivots. If the issue persists, the visor may need adjustment or replacement.
- Helmet Feels Too Loose or Too Tight: Refer to the sizing guide to confirm you have the correct helmet size. If the fit is slightly off, the removable padding might be adjusted or replaced with different thickness pads (contact support for options).
- Visor Fogging: Ensure the ventilation system is open to allow airflow. Anti-fog treatments or inserts can also be used on the clear visor.
