Mask Tips:
Scrub the interior lens of your mask after purchase with toothpaste or a non-abrasive cleaner to prevent unwanted fogging.
Over-tightening a mask will cause mask leakage.
Bugs eat silicone, make sure to store your mask in a plastic mask box.
Consider prescription lenses or optical inserts if you normally wear prescription glasses.
Rinse your mask thoroughly with fresh water after each use. Keep out of direct sunlight as much as possible.
