Setup
1. Helmet Sizing and Fit
A properly fitting helmet is crucial for safety. To determine the correct size, measure the circumference of your head approximately 1 inch above your eyebrows. Refer to the manufacturer's sizing chart. The helmet should fit snugly around your head without causing pressure points. It should not move freely when you shake your head.
2. Chinstrap Adjustment (Fidlock System)
The Altitude 2.0 features a Fidlock magnetic chinstrap for easy and secure fastening.
- Place the helmet on your head.
- Bring the two ends of the chinstrap together. The magnetic buckle will automatically align and snap into place.
- Adjust the strap length so that it is snug under your chin, allowing only one finger to fit between the strap and your chin.
- To release, slide the red tab on the buckle away from the helmet.
3. Visor Adjustment
The visor can be adjusted to your preferred angle. Loosen the screws on either side of the visor, position the visor, and then retighten the screws securely.
4. GoPro Mounting
The helmet includes integrated capability for GoPro camera mounting. Utilize the designated mounting points on the helmet for secure attachment of your action camera. Ensure the camera is firmly attached before riding.
Operating
Wearing the Helmet
Always ensure the helmet is worn correctly and securely fastened before beginning any activity. The helmet should sit level on your head, covering your forehead, and not tilted back.
Ventilation Control
The Altitude 2.0 helmet features upper exhaust vents and a larger chinbar intake for optimal airflow. These vents are designed to help regulate temperature and reduce fogging. While riding, you may notice airflow through these channels, which is normal and intended for comfort.
Maintenance
Cleaning the Helmet Exterior
- Use a soft cloth dampened with mild soap and water.
- Avoid abrasive cleaners, solvents, or harsh chemicals, as these can damage the helmet's finish and materials.
- Rinse thoroughly with clean water and air dry.
Cleaning the Interior Liner
The interior comfort liner is typically removable for cleaning. Refer to the specific instructions for removing and re-installing the liner. Hand wash with mild soap and water, then air dry completely before re-installing.
Storage
Store your helmet in a cool, dry place away from direct sunlight and extreme temperatures. Avoid placing heavy objects on the helmet, which could deform its shape.
