STREAM 2 SEA Mask Defog, Reef Friendly Defogger Coating Anti Fog Mask for Glasses, Snorkel Mask, Scuba Divers, Ski Goggles and Sports Glasses Equipment

Buy this if you have trouble with your face mask or goggles fogging! I have tried a few in the past but this one really is the best I ever tried. I purchased it based on other's reviews and would totally agree. I used a good amount and it lasted through a few on and offs of the face mask. It was so nice to snorkel without the constant stopping to use spit because my antifoam wore off almost immediately before. I highly recommend this brand!!

Works like a dream! I rub a couple drops all over the inside of the lens and let it sit for a few minutes the. Rinse it out and go. Zero fogging issues and a lovely, clear snorkeling session. Highly recommend.

Works like advertised, which is refreshing

Two treatments seems to clean mask

I used this kit on a trip to the Florida Keys and it works as stated - helped keep the fog off the mask lens. There was sufficient quantity for our multiple skin diving outings.
