Blue Holic Tip 🌊

A small amount goes a long way. You don’t need to fully rinse it out—leaving a light film is what helps prevent fog during your dive.

Crystal-Clear Vision, Dive After Dive

Designed specifically for select GULL masks, the GULL Anti-Fog Film helps prevent lens fogging while maintaining exceptional optical clarity. Once installed, the reusable film dramatically reduces fogging without the need for traditional defog solutions, allowing you to spend more time enjoying the dive and less time clearing your mask.

Each film is precision-cut to fit its corresponding GULL mask, providing seamless coverage and long-lasting anti-fog performance.

Why We Love It

Even the best dive masks can fog under the right conditions. The GULL Anti-Fog Film provides a simple, long-lasting solution that helps keep your vision clear throughout your dive.

Unlike liquid defog that needs to be reapplied before every dive, these films remain installed inside the mask and continue working dive after dive with minimal maintenance.

They're especially useful for underwater photographers, instructors, freedivers, and anyone who wants one less thing to worry about before entering the water.

• Long-lasting anti-fog performance

• Precision-cut for an exact fit

Blue Holic Tip 🌊

A properly installed anti-fog film can dramatically improve your diving experience. We still recommend rinsing your mask before each dive, but with the film installed you'll spend far less time dealing with fogged lenses and more time enjoying the underwater world.
