We’re here to help resolve any fogging problems you’re experiencing. Fogging happens due to moisture, and we need to figure out where it’s coming from.
First, is the fogging on the inside, outside, or in between the two panes? If the fogging is between the two panes, the seal is bad, and the lens would need to be replaced either by our one-year lens warranty or by purchasing a replacement.
Not every goggle is suitable for every face shape.
If the fogging is occurring on the OUTSIDE of the lens, please review the recommendations below:
1. Are you using a breathbox? If not, we suggest using one to divert that breath moisture away from the front of the goggle lens.
2. Is your breathbox over your goggle nose mask? If so, adjust the breathbox to divert your breath downward, so it doesn’t flow to your goggle lens.
If the fogging is occurring on the INSIDE of the lens, please review the recommendations below:
If the fogging is occurring top down:
1. Are you wearing a balaclava? If not, tighten the chin strap to create airflow in the top of your helmet. This will create a “wedge” of air on the brim of the helmet to assist in exhausting the built-up moisture.
2. Adjust the goggle on your face so the foam is directly touching your skin. The moisture is wicking to the balaclava and preventing moisture from escaping inside the goggle lens and new air from circulating inside the lens.
If the fogging is occurring middle out:
Try a heated goggle or another style of goggle. The heat from your face is not escaping inside the lens.
If the fogging is occurring bottom up:
1. Are you wearing a balaclava? If not, tighten the chin strap to create airflow in the top of your helmet. This will create a “wedge” of air on the brim of the helmet to assist in exhausting the built-up moisture.
2. Adjust the goggle on your face so the foam is directly touching your skin. The moisture is wicking to the balaclava and preventing moisture from escaping inside the goggle lens and new air from circulating inside the lens.
Keep in mind these best practices on the trail or in the backcountry to eliminate fogging inside the lens:
- Goggles should be left face down on your machine, not a snow bank, when taking a break. Any moisture (from mother nature or your breath) can get trapped side, be sure to give some proper ventilation to dry out any sweat or moisture. Putting goggles on the mountain grab bar or by your windshield is good.
- Do not put your goggles on your helmet's chin bar. Your breath is escaping through this vent, and the moisture will go directly to your goggles - causing fogging.
- Keep Moving. Staying in motion helps maintain airflow through the goggles. 509 goggles have strategically placed venting (in frame and in lens) to allow moisture to escape.
- Let goggles properly dry before storing them away.
- Adjust your goggles. Make sure goggles are fitting snuggly to your face and that foam has contact to your skin.
- Avoid overly touching the inside of the lens as it can eat away at the anti-fog coating on the lens. Using the goggle cloth bags to store and change lenses is always a good idea!
- Use a breathbox to divert the breath away from the goggle lens.
