Currently using bloc glasses. With a mesh lower for a mouth shield. I feel the main issue is heat and moisture from the mesh somehow coming back up into the eye area. Why I question this is because I’ve used googles with a full seal and still get issues. So… that thought process brought me to using anti fog solutions to coat the lens. I don’t normally run hot or sweaty. So the next thing is to move the warm air completely away from the eye area or increase the area in which the fogging is occurring to help prevent it. I’ve found a company who has them. But no spare lenses or replacement lenses. That’s the but which has put me off. Getting the spares

Fogging is becoming an issue. Any thoughts of ideas on best helmet or googles. Currently have tried fans, dye masks, wileyx googles. Just can not get a good fix for the issue. Tried different coatings. I feel the issue is ventilation! help required
