Prince

The Prince represents the latest evolution in Cressi’s full face mask line, engineered for high-frequency recreational use while integrating advanced respiratory and safety technologies inherited from the Duke and Baron models. The design focuses on maximizing airflow efficiency, eliminating carbon dioxide accumulation, and providing superior user comfort through optimized material selection and ergonomic sealing geometry.

ADVANCED AIRFLOW MANAGEMENT — SEGREGATED BREATHING CIRCUIT

The Prince incorporates a dual-channel respiratory system designed to completely separate inhaled and exhaled airflow. Key engineering features include:

• Dedicated intake channels that deliver fresh air directly to the viewing chamber and breathing zone

• Unique side-exhaust ducts that expel exhaled air directly to the environment, preventing rebreathing

• Continuous airflow circulation to keep the lens chamber ventilated and fog-free

This architecture was laboratory-tested at the Engineering Department of the Polytechnic University of Milan, demonstrating substantially higher airflow performance compared to competitive masks and confirming the absence of CO₂ recirculation.

SAFETY ENHANCEMENT — ZERO CO₂ BACKFLOW DESIGN

The mask’s internal geometry prevents:

• Carbon dioxide backflow into the breathing chamber

• Stagnation zones near the mouth and nose

• Health risks associated with inadequate ventilation

This system solves common safety weaknesses present in many full-face masks on the market, ensuring safe surface snorkeling under all conditions.

FACIAL INTERFACE ENGINEERING — SOFT SILICONE SKIRT

The facial skirt is constructed from hypoallergenic soft silicone, providing:

• Superior elasticity for adaptive sealing

• Increased long-term durability compared to PVC alternatives

• A watertight seal with minimal strap tension

The silicone X-shaped head strap distributes pressure evenly, stabilizing the mask without causing discomfort.

Unlike traditional fabric straps that stretch, absorb water, and lose tension over time, this full-face mask features a durable silicone strap with an integrated buckle system.
Silicone maintains its elasticity and shape even after repeated use, exposure to saltwater, and sun—ensuring a consistent, secure fit dive after dive.

The puzzle-style buckle system locks firmly in place with an audible click, preventing unwanted loosening during use while allowing fast, intuitive release when needed. Even, bilateral adjustment ensures balanced pressure distribution for improved comfort and mask stability.

The result is greater durability, improved performance, and a reliable fit that lasts, session after session—so the focus stays on the experience, not on readjusting your gear.

VISUAL SYSTEM — PANORAMIC POLYCARBONATE LENS

The Prince uses a polycarbonate frame and viewing window, engineered to provide:

• A wide, unobstructed panoramic field of view

• High impact resistance

• Reduced internal volume for clearer sightlines

This prevents the claustrophobic effect common in other full face masks.

DRY-TOP & WATER MANAGEMENT SYSTEM

The Prince integrates:

• A dry snorkel mechanism to prevent water entry upon surface splashes or brief submersion

• Water drainage valves at the bottom of the breathing chamber to expel incidental water efficiently

• A specialized airflow deflector that increases air circulation and eliminates fogging

The Prince is engineered exclusively for surface snorkeling, not for deep diving, where pressure differentials can impair performance.

By combining laboratory-validated airflow separation, premium silicone sealing, and advanced water management systems, the Prince Full Face Mask delivers exceptional safety, comfort, and performance for surface snorkelers seeking a high-efficiency breathing solution.
