U.S. DiversAnti-Fog Clear Gel for Swimming Goggles, Snorkeling and Diving Masks - Powerful Long Lasting Formula, Non Abrasive, Non Toxic - for a Dry, Fog Free Vision (37 ml)

He just told me about some great story while using this- dang if I can remember- that’s what happens when your 67… anyway- he loves it- we live on a small lake- he snorkels all the time and he had me buy 2.

Product works as described! Travels well too!

This anti fog is so so. It is slightly overpriced for the amount that’s in it. I highly recommend using tooth paste. Put enough in the mask or googles to cover the whole lenses and then wash it out with either salt water or fresh water. It will save quite a bit of money using the cheapest toothpaste. I’ve been free diving for 6 hours taking my mask off and not reapplying tooth paste and not having any kind of fogging.

I use this product along with cleaning my googles with dawn dish soap after each use. Lord lasting. Follow the directions.

When it squirted out it came out in a thick line instead of a smooth gel. So when I rubbed it it around on the mask it smeared and did not come clean like other products I have used. It did not keep my mask from fogging up. Maybe it was old?

Worked well for our goggles in the ocean

My favorite Anti-fog product I've used EVER.... This stuff LASTS, I dive for hours on my dive days, usually 6-8 hours and it's awesome. Can't go wrong with this stuff, unless you use too much.

I can't say it absolutely doesn't work, but, I followed the directions to a Tee and the goggles still began to fog after snorkeling for about 30 min... would the fogging be worse if I didn't use it? I don't know.. but I bought this with the intent for it to not fog at all.
