The first thing to do is to read the goggle hangtag carefully. There is a comprehensive section on important goggle care.
For quick reference, here are a few tips to reduce fogging:
- Do not rub the inner lens when wet
- Refrain from resting goggles on your forehead and ensure the goggle sits flush against your face
- Don’t store your goggles when wet
- Don’t hang your goggle from your rearview mirror
