C4 Martian Black Antifog

Martian Black Antifog freediving & spearfishing mask The Martian Black Antifog mask is designed for maximum comfort during freediving and spearfishing. Its medium internal volume reduces equalization effort, for a smoother, more natural diving experience. Wide field of view and hypoallergenic silicone skirt Martian's design ensures a wide, unobstructed field of view. The skirt is made from extremely soft hypoallergenic silicone, ideal for extended dives too. Interchangeable tempered lenses The lenses are mounted using the traditional retaining-ring system on the skirt and mask frame. This allows the lenses to be replaced and also makes it possible to fit prescription lenses. Plasma Antifog technology The tempered glass lenses undergo a double plasma treatment that makes the surface hydrophilic. Unlike traditional antifog sprays, this treatment creates a thin, permanent film of water on the inner lens surface, preventing condensation and guaranteeing clear vision for the whole dive. The treatment is built into the lens, doesn't wear off, and activates simply by soaking the mask in water for about 3 minutes before use. Care and maintenance Even antifog lenses can fog up if the inner surfaces aren't kept clean: avoid contact with sunscreen or oily substances, never touch the inner lenses with dirty fingers, and clean before every use with a neutral, oil-free cleaner or a dedicated mask cleaning product.
