Experience a true panoramic vision with the C4 SKYLINE mask. Its unique single-lens frameless design expands your field of view for an incredible spatial effect, making you feel like you´re not wearing a mask at all.

The revolutionary Plasma Anti-fog technology guarantees permanently crystal-clear, fog-free vision—no sprays needed, just a quick soak. The soft, hypoallergenic silicone skirt provides exceptional comfort and a perfect seal for any face shape, even with a beard.

Lightweight and versatile, it´s ideal for freediving, spearfishing, and technical diving

Its extremely wide field of view offers a true ´´panoramic´´ experience, thanks to a specially shaped single-lens frameless design that expands the visual angle at the top (12 o´clock) and the lower sides (4 and 8 o´clock).

The standard-sized skirt provides excellent fit for both small and large faces, including female divers.

The nose pocket features deep recesses for easy equalization, and the micrometric adjustable buckles allow precise and quick adjustment.

Plasma Antifog Technology.

The SKYLINE mask lenses feature an innovative double plasma treatment, which makes the glass surface hydrophilic.

This creates a permanent micro water film that prevents fogging and ensures crystal-clear vision throughout the dive — with no sprays or maintenance required.

How it works:

• Double plasma treatment on tempered glass.
• Hydrophilic surface prevents condensation build-up.
• Activation: simply soak the mask in water for about 3 minutes before use.
• Ensures a clear, fog-free view during the entire dive.

Advantages:

• Permanent coating — it won´t wear off or fade.
• Constant performance — always clear vision.
• Easy to use — activates just by wetting the lenses.
