Fog-X for Swim Goggles

  • Anti-fog inserts that provide long lasting anti-fog
  • Fits in any goggle
  • Two pairs (four total) of inserts included
  • Time to see where you are going!

We were tired of swimming through a fog. That's why we created Fog-X, the only long lasting anti-fog insert that you apply once and forget. 

It's just that simple. Peel the protective tabs, insert, and swim on!

"I've recently installed an Endless Pool Elite for training and instruction, and there is a very important aspect to pools like this... whatever is in the pool, loops around and will eventually hit you in the face. This includes chemicals and/or spit that you use to prep your goggles.

I've been testing these inserts in various goggles, even my 30-year-old Swedes, and they work great. A quick dip in the water, a little shake to get any extra water out, and put on the goggles. So simple and incredibly effective. Nicely done."

Are the inserts blue or clear?

Clear. There are protective films on both sides of the inserts that need to be removed with the pull tabs. One of these films is blue, but should be off by the time you are ready to swim, leaving a clear insert.

Does the insert fit any goggle?

Yup. The Fog-X insert is small enough to fit in any goggle, but big enough to cover the majority of your vision. A rim of fog may develop around the insert, but this is usually unnoticeable.

How long does the anti-fog effect last?

Over a year! 

My goggles are still fogging up bad on the first use or the insert won't stick on the goggle...

Sometimes, an extra layer of protective films is left on the insert. This keeps the anti-fog or adhesive layer covered up so it won't work. You can try to pry off this extra layer or use a piece of tape to peel it off. If all else fails, just hit us up at for a new pack!

They worked for a few days but are now fogging up... 

The inserts can get dirty quickly. Just rub them real well with your suit and they should clear up right away. Fog-X is very scratch resistant and you won't harm it rubbing with a suit.

My goggles still fog with the Fog-X inserts. How do I fix that?

Fog-X inserts need to be hydrated to maintain a flat layer of water. Dip your thumbs in water and rub the inserts before practice starts.

Can I peel it off and replace it?

Sure. You won't need to, but you could. The adhesive is silicone based and leaves no residue on your goggles. If you need to replace them, simply peel them off and stick new ones in.

Great concept, application flawed

This could be a great product.
I was able to apply only one of the four inserts. The tabs were awkward to handle and placing the inserts in the goggles was a struggle. Pulling off the final tab resulted in the entire insert coming loose or dislocated
A good idea but you need a better installation method

They didn’t stick!

I’m very disappointed in my recent order. They didn’t stick to the goggles (I tried them on multiple pairs of goggles, all different brands). I ordered several packages too, tried almost all of them, and none of them stuck. Goggles were clean. Not sure what changed as my first order almost a year ago I had no issues with.

Hello Acacia,
Thanks for your second order and feedback. Not sure what is wrong, but we will send new ones immediately. If still struggling, please email me directly at so we can talk over the phone and figure out the problem.
Thanks for your patience and support!

They work!

Have been using the FOG-X inserts for a few weeks, and can honestly say: They WORK! I never have to stop to clear my goggles because they’re fogged up.

Tony Korvick

Installed as directed but in South Florida midday heat and cool pool after 75 yards of Masters practice they were already fogged up. Won’t be buying again.

Hello Tony. I'm sorry to hear the inserts didn't work. Please contact us directly at We would like to know more about your inserts and offer new replacements or a refund. Occasionally, the protective films do not peel off properly and a layer is left covering the anti-fog coating. Thanks for your review!

Fog free goggles at last!

Ive tried all the sprays to try to keep my goggles fog free but none worked. These work a treat though. Very satisfied. Just a bit expensive when ordering from the uk.
