Apollo Bio Metal D Class Matte Mask
If standard masks feel too roomy, the Apollo Bio Metal D Class is a smaller-fit option worth trying. Made in Japan, it combines a 95 cc surgical-grade silicone skirt with a slim machined aluminium frame and clear tempered-glass lenses.
Smaller Type-D fit
The D Class is the smaller-fit option, aimed at petite-to-medium adult faces. Its 95 cc skirt has an advanced double-lip edge that spreads contact pressure, while the downward lens angle helps you look towards your equipment. A face-fit check is still the best way to choose your mask.
Made in Japan, with a precision-machined frame
The aluminium-alloy frame provides strength in a slim profile, leaving less frame around your view. Silver, Navy Blue and Metallic Purple have a polished, anodised finish; Matte Black, Lemon, Aquamarine and Peach have a satin, anodised finish. The soft surgical-grade silicone skirt flexes against your face for a comfortable seal.
Tempered-glass lenses
The two lenses are made from tempered glass, strengthened by heat treatment. The narrow 7 mm centre bridge reduces the amount of frame between your eyes, helping the twin-lens view feel more open. These are the standard clear lenses; corrective lenses are available separately.
- Type-D skirt with an advanced double-lip sealing surface.
- Listed internal volume: 95 cc.
- Matte finish on the inside and outside of the black skirt.
- Supplied with a clear protective box.
Care and storage
Rinse the mask in fresh water after each use to remove salt, sand and chlorine. Let it dry in a ventilated place out of direct sunlight, then store it without folding or crushing the skirt. Follow the lens-preparation instructions supplied with your mask and keep grit away from the glass.
Adjustable split silicone strap
The wide, split rear section spreads contact across the back of your head and helps keep the strap in place. Adjust the side buckles for a secure, comfortable fit without pulling the skirt tight against your face.
