C4 mask SKYLINE Antifog

C4 mask SKYLINE Antifog

The name SKYLINE evokes a panoramic vision — exactly what this mask provides.
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 result is an incredible spatial effect and the unique sensation of not wearing a mask at all.

The soft hypoallergenic silicone skirt and frameless structure ensure lightness, comfort, and perfect fit. Ideal for snorkelling exploration freediving or winter spearfishing, where dives are not too deep but a wide field of vision is essential. Also perfect for technical diving, as it allows divers to keep both the equipment and the environment in full view.

The seal is outstanding, even for divers with a moustache, thanks to a carefully designed edge that adapts to any face shape. 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.

The SKYLINE mask lenses feature an innovative double plasma treatment. This innovative for 2026 solution is an alternative to the already known antifog technology using a transparent foil on the inside of the lenses. The plasma treatment makes the glass surface hydrophilic, which prevents the moisture to condense into droplets and fog-up the lens.

It is important for you to know that this new antifog technology requires  prior "activation". Soak the mask in water for three minutes and it is ready.

The plasma antifog technology doesn't eliminate the necessity for you to follow these simple rules:

Instructions for Use and Maintenance of Antifog Masks

Introduction

The lenses of any mask – with or without antifog treatment – may fog up if they are dirty or not properly cleaned.

Masks with antifog treatment are designed to eliminate the need for the initial preparation normally required for all new masks. This treatment removes residues of oils and silicone greases used in the molding of silicone skirts. These residues are the main cause of fogging and are often difficult to remove even after multiple cleanings.

It is important to highlight that antifog masks are equipped with internal films applied directly to the glass, which constitute the antifog system itself: these films must never be removed, scratched, or tampered with, as doing so would compromise the effectiveness of the treatment.

It is important to note that an antifog mask can still fog up if the internal surfaces are not properly maintained.

Usage Recommendations

Preventing lens contamination
• Avoid contact with greasy or oily substances (e.g. sunscreens, oils).
• Never touch the inner lenses with dirty or dry fingers.
• Pool water may leave stains or residues depending on the chemicals present.
• The most common contamination, especially in summer, comes from sunscreen.

1. 1. Managing temperature differences
      • Temperature variations between the inside and outside of the mask may cause condensation.
      • To reduce this effect, wet both your face and the mask before use to equalize the temperature.
      • Typical situations:
      • swimming pools with warm water and very humid environments,
      • sea dives with hot air and relatively cool water.
   2. Cleaning the inner lenses
      • Clean the inner lenses before each use.
      • If cleaning is performed regularly and dirt is minimal, rinsing with running water is sufficient.
      • In case of persistent dirt:
      • carry out a preliminary cleaning with a non-greasy detergent diluted in fresh water (e.g. neutral liquid soap or dishwashing liquid), or
      • use a mask-specific product such as Absolute Cleaner or Antifog.
      • Other antifog products may also be effective, but their performance has not been verified and therefore cannot be guaranteed.
      • As an alternative, the traditional method of applying saliva followed by rinsing immediately before use remains valid.
