STREAM 2 SEA Reef Safe Anti-Fog Spray for Swim Goggles, Snorkel, Scuba & Ski Masks – Defogger for Diving, Snorkeling – 2Fl Oz

We have our own snorkel equipment and have it used for the last few years (we each have very different types of masks). I purchased this for our most recent snorkelcation in early April 2026. For my mask, the spray provided crisp visibility with zero fogging each day I had used it (3 days). On the fourth day, I did not use it and my mask had a little bit of fogging as a result, although fogging has never been a significant issue with my mask. For my husband's mask, the situation was different. The first day his mask had zero fogging, but he experienced significant fogging on the remaining 3 days. To be fair, I think his issue was more related to the overall mask/fit versus a problem with the spray. I highly recommend giving this spray a try! How to use: before going into the water, we sprayed a few times into each lens of the mask and rubbed it around. We then used bottled water to swish around in the lenses and rubbed to remove streaks. Then we discarded the liquid and used a towel to blot the excess water inside of the mask. We will use this spray for future trips!

Great product! Worked great keeping our snorkel masks from fogging. Snorkeled for hours without having to reapply. I highly recommend.

I love how it keeps my goggles from stop fogging up . I would so get it again especially if you are on a swim team to compete . It will really help out a lot .

Used this for some light snorkeling out of a cove. Applied per given instructions and seems to get the job done, you don't seem to need a lot to get everything in. I was able to see just fine with the applied anti-fog during my snorkeling session and for a cheap solution to stay underwater longer this was up to my standard. My only gripe is that after about an hour I would start getting some fogging again and having to clear my mask while in the water. Other than that, this is a solid option for the money.

Great product! Instructions are on the bottle 🙂

Auntie folk spray is working fine, for a few times during the swim it’s clear underwater and didn’t have any fog One lenses

I picked up the STREAM2SEA Anti-Fog Spray not for swim goggles, but for my motorcycle helmet visor since winter riding gives me a ton of fog buildup. The spray kind of works — it definitely reduces fog, but not as much as I hoped for riding in cold temps. My biggest gripe is the application process. The directions feel a bit complicated for something that should be quick and simple, especially when you’re trying to treat a helmet visor before heading out. I really wish the instructions were more straightforward. To be fair, I’m pretty sure this spray would work great for its intended use on swim goggles, and I do like that it’s safe for different types of lenses. It’s versatile, environmentally friendly, and has potential — just not the easiest option for motorcycle gear. Overall, it’s decent, but I’d love to see a more user-friendly application method.

For those that swim competitively, like me, this product is drcent. I thought it was a spray type bottle but it shoots out in globs. It works for a little bit but have to make sure it sits in your lens for a little bit before rinsing.

Fungerade hur bra som helst på billigare snorkelmask. Bara skölj av ordentligt med vatten innan användning.

Am besten vor jeder Benutzung auftragen aber dann hält es was es verspricht. Kein Beschlagen der Brille. Ich würde es wieder kaufen

J’ai essayé plusieurs autres marques, mais celle-ci ce distingue le plus par son utilisation, son efficacité ainsi que le peu de produits à être utilisé.

Works great. Snorkelled for 3 hours in a row without any fog. If you take a break would recommend applying the gel again before heading back in the water
