With exposure to sunlight, saltwater, and chlorine, synthetic gaskets degrade over time due to the loss of structural oils called plasticizers. Proper protection with UV Tech™ is essential for maximizing scuba gear life.

Mask fogging results from warm humid air inside the mask meeting a lens surface cooled by water. Warmer air is capable of holding more water vapor (water in gas form) than cooler air. Therefore, when air is cooled, a portion of its water vapor condenses into tiny liquid droplets, or “fog”. McNett® Anti-Fogs prevent fogging by creating a thin, invisible film on the lens which creates a “sheeting effect” - eliminating the formation of condensation droplets.
