    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!

    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.


    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.

    Good product works on glasses when wearing a mask

    Bought fog x for swim googles but have not gotten a chance to try yet due to the closure of pool. However, I work in healthcare and have been using fog x on glasses to keep fog away when wearing mask all day. It works just wish was larger.

    Hello Owen,
    We are glad to help! Thanks for the feedback. We have a larger version on the way even now and would be glad to send you one as soon as they arrive.
    And thank you for working the front-lines!

    Amazing product!!

    Great product! You will not be disappointed 😊
