C4 Skyline Mask with C4 Mistral Snorkel

Paired With C4 Mistral Snorkel

• Description

  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 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 beard or mustache, 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.

• Specifications

  Plasma Antifog Technology

  • The tempered glass lenses undergo a double plasma treatment. This creates an extremely thin hydrophilic layer on the glass surface.
  • When in contact with water, the surface prevents condensation by forming a uniform micro water film.
  • The result is a consistently clear view throughout the dive, without the need for sprays or repeated treatments.

  Advantages

  • Permanent treatment: Integrated into the lens — not a coating or spray — it does not wear off and requires no reapplication.
  • Consistent performance: Provides a clear, fog-free view during the entire dive.
  • Ease of use: Simply immerse the mask in water for about 3 minutes before wearing it.

• Care Instructions

  Preventing Lens Contamination

  To maintain the antifog effectiveness:

  • Avoid contact with greasy or oily substances (such as sunscreen, cosmetic or protective oils).
  • Never touch the inner lenses with dirty or dry fingers.
  • Be aware that pool water may leave marks or residues due to dissolved chemicals.

  Managing Temperature Differences

  • Temperature differences between the inside and outside of the mask can cause condensation.
  • To minimize this effect, wet both your face and the mask before use to equalize the temperature.

  Common situations where fogging may occur:

  • Warm pool water in very humid environments.
  • Sea dives with warm air and cooler water.

  Cleaning the Inner Lenses

  • Clean the inner lenses before each use.
  • If maintenance is regular and the dirt is minimal, a rinse with fresh water is sufficient.
  • For persistent dirt, perform a preliminary cleaning using:
    • A non-greasy, mild detergent diluted in fresh water (e.g., dish soap — see tutorial video), or
    • A specific cleaning product for masks, such as Absolute Cleaner or Extreme Antifog.
  • The use of other antifog products may be effective, but is not tested nor guaranteed.
  • Alternatively, or in addition, you may use the traditional saliva method: apply a small amount of saliva to the lenses, then rinse thoroughly just before diving.
