Hi BigH,

The best advice we have from our AF coating supplier is to dip the goggle in water first to help create a barrier between the inner lens and your face. This helps activate the coating. Fogging is caused by a temp and humidity difference between your face and the inner lens, so getting the lens wet first can help. We use the same AF process (and in fact the same AF supplier) as one of our more established competitors from the pool swim world. It's a proven process, so there isn't anything different we're doing there.

Give that a shot and let me know if it's a persistent issue. If so, please ping us at support@rokasports.com, and we'd be happy to swap it out.

Best,
Rob
