“Sea” Clearly with this EcoConscious Mask & Goggle Defog, made with only the safest ingredients for our planet.

  • Reef-friendly, Non-toxic
  • Professional Strength
  • Biodegradable reef safe formula
Tested and Proven Reef Safe, PCR, Fragrance Free

Confession: My spit is defective.  It doesn’t matter how much I prepare my mask, either. I have scrubbed and scrubbed, “toothpasted”, flamed, and scrubbed some more.  I always fog.

So, I jumped into the lab and whipped up a batch using our tested and proven eco-safe ingredients. I like my defog a little more thick and believe the guar gum can also leave a slight film on the lens to help reduce fogging.  It worked great for me, so I started giving out samples to friends and Divemasters – they all loved it!

Our final mask defog is a product that I can be proud of and I’m ecstatic to bring to the dive community. The defog itself holds up to its name multiple dives in a row, and our bottles are sustainably made from sugarcane resins, with the new caps made from recycled flip-flops. Our mask defog is just another way to protect what we love.

Usage:

Directions for Dive Mask & Goggles: Apply a small amount on the inside of the lenses. Use your finger to rub completely over the lens. Add a small amount of water, and rub the defog to remove any streaks. Pour the liquid out when ready to dive. Some bubbles remaining are good.

For glasses, safety goggles, ski goggles, sports masks and more: Apply a small amount on the inside of the lenses and lightly rinse or gently buff with soft lens cloth.

Caution: Although this product is formulated with safe and gentle ingredients, avoid direct contact with eyes. If irritation occurs, rinse eyes thoroughly with water. Consult a physician if irritation persists.

    Just tried out the Defog on a trip to the Philippines…longest run was 10 dives (2 days) without reapplying,but I found that a pea size drop on each lens and I didn’t need to put anymore on the rest of the day (5 dives). Plus everyone on the boat tried it and loved it also.

  2. Tonya Colson

    This mask defog actually works! It only takes a small amount, so a bottle will last a long time, and it’s in eco-friendly packaging. This product is fantastic- based on my experience with this mask defog, I’m definitely going to be trying more Stream to Sea products in the future.

  3. Christene Main

    I picked up some of the new Stream2Sea mask defog, and brought it with me to Cozumel. Shared it around on the dive boat to get feedback and the results were overwhelmingly positive. Not only is it biodegradable and reef safe, it freaking works. Some said it was even the best stuff they’ve ever used!
    I’ve been a big fan of their sunscreen, hair products, and body wash for a while, and this just shows they really know how to knock it out of the park with quality and sustainability!

    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!!! ❤️‍♀️

    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!

  6. S/V Ronya

    This is the best defog on the market, and I have tested most of them. It keeps your mask clear, doesn’t sting in the eyes, and best of all you can use it knowing you are not harming our beloved reefs!

  7. Gwen Colvin

    Love this product! I use it on more than just my mask and diving. I use it on eye glasses, goggles, face shields, at work, and more. It does bother my eyes either.

    I am loving the mask defog! I dive in a very cold environment ( Air -10C and water 1-2C during the winter months) and this product has performed flawlessly. I put some on my mask (and leave it on) when I am getting my gear ready. I give my mask a quick swish in the ocean to acclimatize to the cold as I am entering the water and I am good to go. No fogging, no mask freeze up and no soap in my eyes!

  9. Rose Z

    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.

    Recently took a trip to a tropical island with shore diving. Applied it before the 1st dive each day and it worked perfectly for several dives all day. Did not irritate my eyes.

  11. Cheryl Blackwood (verified owner)

    Tried the defog before a dive trip to the Bahamas and it worked great. Be conservative with your use and follow the instructions and you will have excellent results.

  12. JW (verified owner)

    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.

  13. Your review is awaiting approval

    Finally, a mask defog I can get behind, not only because it is reef safe, it works so well!! I have been giving this away to friends, and hope everyone eventually will find out about this fantastic product.
