Setup and Sizing
Measuring Your Head
To ensure a proper fit, measure the circumference of your head at the widest point, approximately 1 inch above your eyebrows. Refer to the sizing chart below.
Guide for measuring head circumference and corresponding helmet sizes.
Initial Fit Check
A helmet should fit snugly around your head. There should be slight pressure on your cheeks, and the helmet should not move freely when you shake your head. If you feel excessive pressure or discomfort, consider trying a different size. The internal padding will conform slightly over time.

Care and Maintenance
Cleaning the Helmet Shell and Visors
Clean the helmet shell with a soft cloth and mild soap and water. Avoid abrasive cleaners or solvents. For visors, use only warm water and a soft cloth to prevent scratching. Allow to air dry.
Removing and Washing the Interior Liner
The interior liner and cheek pads are fully removable and washable. Gently detach them from the helmet. Hand wash with mild soap and cold water, then air dry completely before reinserting into the helmet.
The helmet features removable and washable padding for hygiene and comfort.
Troubleshooting
- Visor Stiffness: If the visor feels stiff, ensure it is properly seated in its mechanism. Avoid forcing it.
- Uncomfortable Fit: If the helmet feels too tight or loose after initial wear, re-check your head measurement against the sizing chart. Remember that padding will slightly compress over time.
- Excessive Noise: Ensure all vents are closed if wind noise is an issue. Check that the visor is fully closed and sealed.
