Bio Metal Mask (Matte) D Class
The Apollo BIO METAL Mask C Class is a revolutionary mask. Metal Masks set standards for a fantastic fit and outstanding performance. The luxurious aluminium alloy machined frame delivers accuracy and quality without compromise.
A wide range of adaptability by providing the flange lineup ranging from type-A to type-D. The Matte finish type-D flange provides an excellent fit and antifouling property.
Wide field of view characteristics of unique frame machined aluminium alloy.

Type-D (inner volume 95cc)
Incorporating the opinions of a wide range of other countries has adopted to optimize the flange shape to fit in more widely with people of each country.
The type-D significantly improves the fit around the nose, root of nose and forehead, so the type-D will fit in at a high probability even with the people who are not satisfied with the conventional flanges.
The surface plane is shifted by 5 degrees downward compared with the type-A and type-B so that it improves the downward visibility of the abdomen to the feet. Moreover, it gives a sense of a more stylish appearance.
The double-lip Structure has further evolved to the “advanced double-lip” structure with a larger arc cross-sectional shape which makes the pressure on the outer periphery of the face more gradually and progressively weaken toward outside so that it hardly leaves marks on the face.
Optimizing the shape and length of the lip under the nose to prevent displacement of the mask while effectively preventing the entry of water when pinching the nose for ear clearing.
Our patented technology “brilliant-and -smoke finish” has also further evoluted. The outside surface is matted finish for easy cleaning, preventing adhesion of dirt and Virile appearance.
Type-C (inner volume 110cc)
The type-C design is a universal shape to suit everyone the most, which has been adopted since the introduction of the bio-metal mask. Its merits are soft fit and ease of ear clearing.
It will ensure an effective wide field of view to the travelling direction in the water as the lens surface plane is set slightly upward.
Type-C is the first launch of the flange in the bio-metal series, and it has been the best-selling design.
The outside surface is matted finish for easy cleaning, preventing adhesion of dirt and Virile appearance.
A lip is the periphery of the diving mask flange in contact with the face. The double-lip Structure has one additional lip toward the inside of the flange in addition to the conventional lip that is structured toward the outside of the flange. The double-lip Structure doubles the total area in contact with the face, and consequently, it reduces the contact pressure to the face and improves the waterproof.
Advanced double-lip Structure
The “advanced double-lip” structure has a larger arc cross-sectional shape periphery which makes the pressure on the outer periphery of the face more gradually and progressively weakened toward the outside so that it hardly leaves marks on the face.
The flange of the stabilizer structure wraps the frame around the lower and side surfaces of the frame. This Structure has overcome the weakness of a conventionally shaped flange that tends to bend from the root of the connection portion with the frame. As a result of this overcome, the stabilizer structure has achieved very stable mounting while the inner volume remains at a minimum.
The curved circumferential surface effectively uses different curves at the inner and outer surfaces so that the periphery gradually changes the thickness of the cross-section. This Structure optimally controls the amount of the bend and contact pressure of the circumferential surface when mounting.
Matt Finish (type-D, type-C Black)
It is matte finished black on both inside and outside. It is the best-suited diving mask for those who dive under a situation where any reflection of light is inherently prohibited or undesirable. It gives dignity to the professional tool and protection against the adhesion of the dart.
Wide vertical view
The frame is tilted downward by a further five degrees compared with type A and B, and the lens frame is set as close as possible to the forehead. This Structure has gained a downward field of view and consequently achieves a wider vertical field of view.
It is designed to fit more diverse face types compared to other models by selecting material and optimizing the size and shape of the area that fits the face. Its wearing feel is very soft and better to get used to.
Machined Aluminum Alloy Frame.
The luxurious aluminium alloy machined frame delivers accuracy and quality without compromise.
The high-quality frame material with a high degree of accuracy is produced by a luxurious machining process, and the surface thereof is subjected to a plasma coating (part of bio-metal mask pro) or hard alumite processing (aluminium frame) in order to much improve luxury and durability.
Wide 3D vision with Metal frame – in the world (Design Patented)
The metal frame attains the width of the centre portion of frames as only 7mm. It feels like a single lens mask.
Polished by craftsman in Japan
Metal frame especially “Migaki (polished) by Craftsman’s hand.
Only underwater mask Crafted in Japan.
Stick to the Lens
Another feature of the bio-metal mask is wide lineup of lenses.
1-Standard lens made of the tempered glass.
2-Polarized lens – laminated – high quality polarizing plate with an excellent polarizing property.
3-Highly durable bio-AR lens suppresses surface reflections to minimum by the multilayer coating.
4-Wide range of the off-the-shelf vision corrective lenses made of optical glass.
It is possible to choose a lens that suits you from this lens lineup.
Silicon Anti-adhesive Sheet
The silicon component volatilized from silicone rubber will stubbornly adheres to the inner surface of the mask lens. It is a thing quite difficult to remove . To avoid this , we put the silicon anti-adhesion sheet on the inner surface of the mask lens at the time of manufacturing.
Because of the low coefficient of viscosity with this protection sheet, the sheet can be easily removed and also repeatedly reused. After the mask is used , wash and dry the mask, then put back the protection sheet on the inner surface of the maks lens. It minimizes the occurrence of fogging due to the volatilized silicon even after long-term storage.
