This mask is designed for freedivers and spearfishers who are looking for a panoramic field of vision and reduced bulk thanks to its frameless design. This mask is not ideal for divers who require corrective lenses or scratch resistance equivalent to tempered mineral glass.
Frameless design: Yes (Score: 5/5) Curved panoramic lenses: Yes (Score: 5/5) * Internal volume specification: Data not documented (Score: 3/5)
This model incorporates a silicone skirt with Advanced Fit Technology, using textured bands to improve adhesion and skin comfort. No statistical studies guarantee a universal fit.
Skirt material: High-quality silicone (Score: 4/5) Facial fit technology: Advanced Fit Technology (Score: 5/5) * Universal seal prediction: No guarantee without testing (Score: 3/5)
The Plexisol polymer lenses allow for specific curvatures but limit hardness and optical compatibility. No original mounting options are documented for corrective lenses.
Lens material: Plexisol polymer (Score: 3/5) Original optical treatment: Standard, without correction (Score: 3/5) * Compatibility with corrective lenses: Not documented (Score: 4/5)
Factory anti-fog treatment: documented for Plexisol (Score: 4/5) Scratch resistance: documented (Score: 4/5) * Material sensitivity to maintenance: high (Score: 4/5)
The ergonomic strap distributes pressure on the occiput. The micro-buckle system allows for easy adjustment, even with gloves. Direct attachment to the mask skirt promotes stability.
Occipital strap design: ergonomic (Score: 5/5) Micro-buckle system: easy adjustment (Score: 4/5) * Accessibility of adjustments: suitable for use with gloves (Score: 4/5)
The model is supplied with a rigid EVA case resistant to corrosion. The absence of an external rigid frame reduces the risk of mechanical damage but requires careful storage.
Rigid transport case included: yes, made of EVA (Score: 5/5) Mechanical resistance of the structure: good without a frame (Score: 4/5) * Protection against scratches during storage: requires the case (Score: 3/5)
The suggested retail price observed on August 18, 2026, ranges from €79 to €89, which is consistent with the technical specifications and the included rigid case. Price range observed: €79 to €89 (Score: 5/5) Market availability: widely distributed (Score: 4/5) * Overall price consistency: high (Score: 4/5)
Plexisol lenses offer the flexibility necessary for panoramic designs, but they are vulnerable to scratches caused by sand. Rinsing with fresh water and using a hard case are required. The lack of optical correction and the need for a morphological fitting complete the list of important considerations.
This comparison helps you compare the models. However, it cannot tell you if a mask is suitable for your face. Before buying, place the mask on your face without the strap, inhale gently through your nose, and check that it stays in place on its own, without any pressure points or leaks. This step represents more than 80% of the actual importance of your purchase. If the skirt does not fit your facial structure, no ultra-clear lens, anti-fog treatment, or buckle system will compensate for the problem.
Safety relies on visual communication between dive buddies. Tinted, mirrored, or filtered variants reduce light transmission and alter the readability of facial expressions. Using a standard clear lens remains the best option to preserve optimal non-verbal communication.
Cleaning the Plexisol requires mild products without abrasive solvents. Rinsing with clear water after each dive removes salt. Storing it in the hard case protects the structure.
Aqualung offers the Aqualung Reveal X1 for recreational diving, which uses tempered mineral glass and a traditional frame. You can find comparisons on the global mask comparison tool.
