FROG SPIT Anti-Fog Concentrate | 2 oz. Bottle of Anti-Fog Solution | Anti Fog for Glasses, Goggles, Face Masks, Helmet Face Shields

Goes on dry and works great. Apply sparingly as a lot can come out with a little squeeze

Good product

For my experience, this product did not work as I needed it to work. I used on my Zeiss dark visor for the Giro Vanquish. Left the lens too smeary and smudgy. Had to wipe it off. Today riding in the fog and high humidity I am still fogging up. 2 stars cause it was delivered on time and easy to apply. Minus 3 stars for smearing too much on tinted Zeiss visor. I can see this working for underwater goggles but not for a tinted road cycling visor. Will keep looking for a lighter more clear product.

The best of all similar products on the market. Doesn’t require anything more than a drop and doesn’t irritate your eyes.

If you are going to use a defog, this is the one I would use. That said, I have found that it does not work any better/longer than just using spit. I got this defog in hopes that it would keep me from having to re-defog every time we get out of the water and move spots when snorkeling, but I have found that I still need to. Because it doesn't work any better than spit, and it's just another thing to add to my gear bag, I have quit using the product. However, if the idea of spitting in something you are going to wear on your face, or at touching your own spit, then this is a good option for you. Otherwise, I would just stick with spit.

Works.

Works well for swim goggles. I put a drop in each goggle and rub it itn before a swim and I am fog-free for the whole work out. Just a one star deduction because it's easy to leave this type of cap open accidentally. Lost all of my "spit" that way!

Use this for scuba diving and snorkeling. no problems. Performed as expected.

This stuff is great, if I had the time and energy I would milk my own frog, but it don’t and it’s better than my spit bully a mile. The price is reflected on the amount of frogs they milked to get the goo but you only need a drop each time
