Say goodbye to constantly wiping off mist from your goggles
The Threo spray fights the problem of blurry vision caused by humidity. Once applied, our defogger creates a protective layer on your glasses, letting you see clearly through them. This brings added comfort to your swimming or diving sessions. Boasting versatility, the spray can be used with various types of goggles, masks, and binoculars.
Improved visibility
Our spray ensures that your diving glasses remain fog-free. By creating a hydrophilic bed on the lens it prevents condensation from forming. You get clear visibility underwater without needing to clean your goggles. This provides both comfort and safety, reducing the risk of losing vision during water activities.


Easy application
Using the Threo defogger spray is a breeze. With just one spritz on each lens, our device creates anti-fog protection that lasts throughout your entire dive session.
Portable
The Threo spray's compact size makes it easy to store in a sports bag or backpack. This allows you to carry the tiny bottle with you wherever you go.
