Cressi Quantum and Itaca Ultra Dry Mask and Snorkel Set

A high-end set for visibility and fog control

The Cressi Quantum + Itaca Ultra Dry pairs a low-volume mask with a thermoregulating No Fog system and a float-operated dry-top snorkel. Designed to combine visibility, a stable fit and mouthpiece comfort.

Technology with practical benefits

• No Fog: redirecting warm air. Membranes around the eyes and nose guide exhaled air away from the lenses. Two external heat exchangers bring the internal temperature closer to the water temperature, helping moisture collect before it reaches the glass.
• A better downward view. Big Eyes lenses tilt at 15° and extend towards the cheekbones. Cressi states an improvement of over 30% in downward visibility compared with a conventional mask.
• A stable, enveloping skirt. A progressively thinner sealing lip improves adaptation; the lower seal is shaped to limit water entry while retaining comfort.
• Compact frame and pivoting buckles. The design brings the lenses close to the eyes and reduces internal volume. Flexible elastomer connects the buckles to the frame for stability without deforming the skirt.
• Itaca Ultra Dry: dry top and easy clearing. A float valve closes when the top is submerged. An elliptical purge membrane helps clear water, while the silicone flex section positions the mouthpiece without interfering with a regulator.

Set specifications

To get the best from No Fog, Cressi recommends careful lens cleaning before first use with Prenofog or a manufacturer-approved cleaner, followed by an alcohol-free anti-fog product before diving.
