How to take care of your Brunotti ski goggle To maintain the quality of your goggles, it is important to cover them with a case. To optimize the protection, make sure to get hold of a hardcase. Especially when you store the goggles in a bag. Whenever the goggles become foggy during your ski trip, heating is your answer. Fogginess arises between the two lenses in your goggles. When placing your goggles next to a medium warm heating, the fog will evaporate. This prevents the goggles from fogging up in the future.
