500 PSI Mask Defog cleans and defogs your scuba/snorkel mask at the same time, allowing you to focus on your adventure. It’s long-lasting, wet or dry application formula allows you to apply it before your first dive of the day and enjoy up to three dives that day without needing to re-apply. Less work, more fun. And with the convenient 2 oz travel size, it won’t take up too much space in your gear bag. 

New to mask defogging? A little goes a long way. A dime-size amount in each lens will do the trick. Rub it in with your finger (no gloves) and rinse. If you just bought a new mask, don’t forget your 500 PSI Mask Scrub. All masks have a film in them, applied by the manufacturers, to help protect them during shipping. You’ll want to use the mask scrub to remove the film before your first use or you’ll spend your dive clearing your mask.
