Perhaps the warm moist air you breath out is condensing on the inside surface of the goggles. You might do better with a combined mask that doesn't allow your outgoing breath to touch the inside of the goggles or separate goggles and breathing filter. The goggles might have a filtered opening to allow water vapor from your skin to escape, or they might be part of the incoming airpath. Outgoing air might bypass the filter to avoid condensation there. Nick
