Professional Mask Defog

Took a bit to nail down the best way to apply but it works great and doesn't hurt my eyes if it gets in!

Works just perfectly, no smell, no damage to the coral reef, no fog at all, perfect!

We’re so happy it kept our full face masks from fogging!

This product is great! My goggles that I use for my triathlon races don’t fog up and my Cressi brand masks for scuba diving don’t fog up at all. I’ve had this product for over a year now. I would purchase more of this product.

I’ve been wearing the mask for 10 minutes and there isn’t any evidence of fog in the slightest. Crystal clear! The size of bottle is going to last a long time. Makes me wonder if this stuff ever wears off or if this mask is just permanently defogged. My mind is blown.Anybody that gave this less than 5 stars didn’t apply it correctly. I did 5 sprays on this mask, rubbed in around with my finger, let it sit for a minute of two the quickly let water run over it for not even a second. Then dry with a hair drier or heat gun. Works perfectly. And this stuff can be used on several applications! Great stuff! Worth every penny!

As a dive pro and Mermaid, this is the best defogger that I have used. Received it as a gift at MerWeek2022 from the lovely Mermaid Megan

Besides good ol human-generated spit, and spit doesn't cut it sometimes. I've had divers tell me over and over again that this is the BEST Defog they've ever used... And I agree!
I love all the Stream2Sea products for their reef safe guarantee, but the Defog has a special place in my heart for making my life so darn easy. ❤️❤️❤️❤️

Best defog around! Was on a trip with 10 divers in Roatan. By end of day 1 they were all using the Strean2Sea defog. The small bottle is super long lasting, we used it on more than 175 dives and still enough to take home. Nobody wanted anything else, knowing how good it was and that it wasn't harmful to the reef and the critters on it.

This product is amazing and I try to convert every diver, snorkeler and dive operator to switch. Having great luck so far. It really is the best; I dive for multiple hours at a time so it's great to know I am helping to protect our ocean.

I bought some Stream2Sea Reef Friendly Mask Defog, along with a bottle of 500-PSI Mask Defog gel. The Stream2Sea is a thinner gel, but works better than 500-PSI. No issues with eye burn at all. Works great. Highly recommend!A dive buddy "lent" me some of his 500-PSI Mask Defog last year, after noticing my struggle with the dive boat anti-fog (dish soap). It worked better than soap, and zero issues with eye burning. My local dive shop sells and swears by the 500-PSI, so I bought my own bottle. 500-PSI is a very thick paste. I found it difficult to rinse my mask glass clear when I was ready to dive in. The Stream2Sea was so much easier to apply, rinse, and provided excellent mask anti-fogging, each and every dive.I just returned from the Caribbean, where I did 15 dives, between 12m/40ft - 28m/90ft. I used both the 500-PSI and the Stream2Sea on alternating dives. The Stream2Sea goes on easier, clears easier, no eye burn at all, and works better than 500-PSI, especially if you're doing multiple dives on the same day. Plus, Stream2Sea is (stated as) reef friendly. The Stream2Sea anti-fog quickly became my go-to for dives, both shallow and deep. I'll stick with the Stream2Sea Mask Defog gel going forward for all my diving. Great product.PADI Advanced Open Water certified diver

Love this defog! I find it works best when I put a very thin coat on my mask while getting my gear ready and let it dry. Because it dries clear, and if I manage to not leave any steaks, I can often jump in the water without the need to rinse off my mask. Works just as well as any other defog I have tried, and this one is safe for all the critters in the ocean. The travel size is perfect to keep in my mask case.

We purchased this to use on our snorkeling masks for the whole family. With this defog, we had absolutely no mask fogging issues whatsoever. Remained clear no matter what we did with our masks. We used to use baby shampoo, but had fogging problems in both the pool and ocean especially after the mask got flooded. Our masks were perfectly clear for the whole afternoon of snorkeling. I have to say that I was initially skeptical but no more. Unlike 500psi or SeaGold, one bottle of this stuff (2fl oz) will last a long time. You use much less product and it's much easier to apply.

I used this product on my scubapro mask and it worked perfectly my mask didn't fog up once

During this pandemic I find myself wearing a face mask for 8-10 hours a day and occasionally during that time, needing to wear my reading glasses for computer or close up work. Having tried the shaving cream or baby shampoo trick (which do kind of work but are not the best choices), I discovered Stream2Sea. I have been using their Hand Sanitizer and LOVE it, so I thought I would try this product as well. I love that their products are environmentally friendly. I am so happy with this product. I highly recommend Stream2Sea!

I got this product to use on masks I am making/donating to teachers and health care workers. The masks allow for their mouths to be seen while still offering protection. The problem was that the "window" part would fog. I apply this product before delivering the masks so that won't happen. School starts soon and I was trying to get more of this product quickly. I don't want the teachers to have to come out of pocket to reapply the product when necessary. I contacted the company asking for the closest brick and mortar store I can go to to get it quickly. They immediately responded with "Give us your address and we will donate some bottles". So not only is it a great product that is eco conscious and non-toxic that works, it comes from a great company. Highly recommend.

On Saturday I used Stream2Sea Mask defog on an 11 hour exploration cave dive. I was really happy to not have any fogging issues for the entire dive! It's also awesome that it's eco conscious and doesn't added to the pollution of our amazing springs! Thanks Autumn for the awesome product!

thank you for creating such a wonderful product in your mask defogger ... in 30+ dives on this sojourn I have yet to have a foggy mask ... this has not happened to me before!! I have shared it with all the people I can on my various dives and it has not failed me. I almost gave my bottle away once but realized “I’m not that nice” and I still had more dives ahead of me If you are someone who sufferes from foggy mask and cares about the ocean and the creatures we want to keep around because that is why we dive ... this product will not let you down!!! ❤️‍♀️

I have tried numerous defog products and Stream2Sea outperforms them all! Highly recommend.

Best defog I've ever tried! It's what I trust to keep my mask clear so I can focus on my photography. And knowing that the ingredients are Reef Safer brings me joy 💙

Works great

Never had good results with my spit, retail Spit, or several other brands - but just used this for 3 different hour-long snorkels in Baja and it was flawless - can't say enough good things about it. After paying all the money to get to somewhere amazing, it's really about actually seeing the things, and this mask defog is perfect!

Great product to defog those masks when diving and snorkeling

I will be using this which is safe to the ocean and coral. It’s the best

I’ve had cataract surgery lasik (multiple times) and other laser procedures on my eyes. This is the only product I trust to be reef safe and not burn my eyes. I love it!!!!

I have tried quite a few, but this gel is by far the best. No need to reapply every time and works both in the pool and open water.

Works very well on keeping lenses from fogging up.

This is the best Defog I have ever used and I have been diving for over 35 years.
