4. Setup
4.1 Sizing and Fit
Proper fit is crucial for helmet safety and comfort. Refer to the size chart below to select the correct helmet size based on your head circumference.
| Brand Size | Head Circumference (cm) |
|---|---|
| XS | 48.5 - 52 |
| S | 52 - 55.5 |
| M | 55.5 - 59 |
| L | 59 - 62.5 |
To check the fit:
- Place the helmet squarely on your head, ensuring it covers your forehead.
- Adjust the internal fit system (if applicable) until the helmet feels snug but not uncomfortably tight.
- Shake your head gently. The helmet should not shift significantly.
- Fasten the chin strap securely. It should be tight enough that the helmet cannot be rolled forward or backward off your head.
4.2 Goggle Compatibility
The Montane helmet is designed for seamless integration with most snow goggles. Ensure your goggles fit comfortably with the helmet, without creating pressure points or large gaps.
- Place your goggles on your face, then put on the helmet.
- Adjust the goggle strap around the helmet. The helmet features a goggle retainer clip at the rear to secure the strap.
5. Operation
5.1 Adjusting Ventilation
The Giro Montane helmet features Thermostat Control Ventilation, allowing you to adjust airflow to manage temperature and prevent goggle fogging.
- Locate the ventilation slider on the top of the helmet.
- Slide the control forward to open the vents for maximum airflow, ideal for warmer conditions or high exertion.
- Slide the control backward to close the vents, reducing airflow for colder conditions.
5.2 Using the Trip Clip
The integrated trip clip and carabineer allow for convenient attachment of your helmet to a backpack or gear bag when not in use.
- Locate the trip clip on the helmet.
- Attach a carabineer (not included) through the clip and secure it to a loop or strap on your pack.
6. Maintenance
6.1 Cleaning Your Helmet
Regular cleaning helps maintain the helmet's condition and hygiene.
- Remove any removable liners or ear pads (if applicable) and wash them according to their care instructions, typically with mild soap and water.
- Wipe the exterior of the helmet with a soft cloth dampened with mild soap and water.
- Rinse with clean water and allow the helmet to air dry completely before reassembly or storage.
- Do not use harsh chemicals, abrasive cleaners, or solvents, as these can damage the helmet's materials and compromise its integrity.
6.2 Storage
Store your helmet in a cool, dry place, away from direct sunlight and extreme temperatures. Avoid storing it in places where it might be exposed to chemicals or fumes, such as in a car trunk on a hot day or near cleaning supplies.
7. Troubleshooting
This section addresses common issues you might encounter with your Giro Montane Snow Helmet.
| Problem | Possible Cause | Solution |
|---|---|---|
| Helmet feels loose or shifts | Improper fit adjustment; chin strap too loose. | Adjust the internal fit system for a snug fit. Tighten the chin strap until it is secure but comfortable. |
| Goggles fogging | Insufficient ventilation; goggle incompatibility. | Open the Thermostat Control vents for increased airflow. Ensure goggles are properly seated with the helmet and are not blocking the Stack Ventilation. |
