You may not know this yet, but the silicone skirt causes an off-gassing effect that results from the manufacturing of the mask. This can cause a thin layer of silicone to accumulate that will result in fogging if not treated properly. The Treatment: Before using your mask, you will need to treat the lens surface on the inside of the mask only. The most popular method is to simply use common white toothpaste, dab some on your finger and rub it on the lens surface. Then rinse off the remaining toothpaste.
