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.

Fog X is completely useless

This product is useless. I used the 2 sets of lenses on 2 different sets of goggles and within 4 laps, they both fogged up immediately. Don't waste your money on this product. Stick to your sprays and baby shampoo.

Fog X works on my goggles

I bought a speedo goggles on August 2023 and after few weeks it started to fog I think because the anti fog coating was becoming less effective and I think because the eyelash touches the lens and oil caused the fog to be foggy. I decided to buy fog X after searching on the internet and I used it for a month and it is working great. I just have to rinse the fog lens with water before I swim for clear vision. I hope it will last long.

These are great

I’ve always had issues with my swim goggles fogging up in open water swim races. I just used Fog-x for a race and had zero issues. I’m a fan!

Love fog x

Have always had problems with fogging. Tried many products and was skeptical about fog x but I can truthfully say it really works. I swim 55 minutes straight and used to have to stop multiple times to clear my goggles but since using fog x I never have to stop. I’ve used it in the pool and in the ocean and it works equally well. I also love the price.

First product that really works to keep goggles clear

Easy to apply, and always keep my field of vision clear for long distance open water swims where I really need to see where I'm headed!
