Say goodbye to foggy lenses. The 500 PSI Mask Anti-Fog Gel is one of the clearest and longest-lasting defog solutions divers rely on worldwide. A single application typically lasts up to three dives in a day, keeping your vision sharp from descent to safety stop.

This gel not only prevents fog—it cleans your mask lens each time you use it, working equally well on wet or dry surfaces. The formula is gentle, non-stinging, and effective for all diving environments—from cold-water training dives to warm-water recreational trips.

Why divers choose 500 PSI Anti-Fog:

• Crystal-clear, long-acting defog performance
• One application lasts multiple dives
• Works on snorkel and dive masks
• Suitable for all lens types and conditions
• Wet or dry application
• Compact 30 ml bottle for easy packing

How to care for your bottle:
Rinse with fresh water after use and let it dry in a shaded, well-ventilated area. Store away from direct sunlight.

Reliable, easy, and diver-tested—everything you want in a mask defogger.
