Product Information
The Atomic Aquatics SubFrame Mask, Slim Fit is designed for scuba and diving that require a precise, secure seal across a range of facial profiles. The Slim Fit design features a smaller, higher nose pocket and a narrower nose bridge to accommodate narrower facial profiles, helping ensure a solid seal on every dive. This version preserves the SubFrame dual lenses, frame, straps and buckle, while refining the skirt to better fit divers with higher cheekbones and smaller noses, based on extensive research and human-factor engineering.
Durable construction supports long-term use with strength and rigidity provided by the internal SubFrame molded directly beneath the surface of the silicone skirt. This design eliminates bulky external frames while maintaining reliability. A stainless steel retainer locks the lenses in place and reinforces the nose bridge area, contributing to a wide field of view and dependable performance for underwater adventures. (US Patent #7,181,778)
Ultraclear lenses offer optics-quality glass with exceptional clarity and high light transmission, with no color distortion. The high transmittance and minimal distortion maximize visibility underwater, particularly in low-light conditions.

Frequently Asked Questions
How do I know if a dive mask fits?
Hold the mask against your face without using the strap, look slightly down, and inhale gently through your nose; a well-fitting mask holds itself in place for a few seconds. Check that the skirt seals all the way around without digging into the nose bridge, and that there are no gaps at the temples or above the upper lip. A mustache can break the seal even on an otherwise well-fitting mask.
Why does my brand new mask fog no matter what I do?
New masks carry a residue on the inside of the lens left over from manufacturing, and defog cannot stick to it, so the mask fogs until that film is removed. The standard pre-treatment is to scrub the inside of the lens with a mild abrasive cleaner or a dedicated mask prep and rinse thoroughly, repeating if it still fogs. Follow the mask manufacturer's instructions, particularly on coated or mirrored lenses.
How do I stop my dive mask from fogging?
Apply defog to a dry lens before the dive, spread it over the whole inner surface, then rinse briefly with water just before you put the mask on. Fogging happens when warm moist air meets a cooler lens, so a clean lens with a thin surfactant film is the fix. Keep sunscreen off your fingers before handling the inside of the lens, because that film fogs badly and is hard to remove.
Why do dive masks need tempered glass?
Dive mask lenses should be tempered safety glass because it resists scratching and, if it ever does break, fractures into blunt granules rather than sharp shards next to your eyes. Untempered or plastic lenses scratch easily and can craze, which is why tempered glass is standard on scuba masks. Look for the tempered marking etched on the lens.
Can I get a dive mask with my prescription?
Yes, prescription options are widely available, usually as masks fitted with stock corrective lenses in set diopter steps, custom-ground lenses installed in compatible frames, or bonded lenses added to an existing lens. Not every mask frame accepts replacement lenses, so check compatibility before you buy the frame. An optician or a dive shop can help translate your glasses prescription into a mask lens choice.
How should I care for and store a dive mask?
Rinse it in fresh water after each dive day and let it dry away from direct sunlight, avoiding anything abrasive on the treated inner lens. Store it in a rigid mask box so the skirt is never compressed or creased, since a set crease in the skirt is a permanent leak. Keep silicone skirts away from petroleum products and prolonged UV, both of which yellow and harden them.
How tight should a dive mask strap be?
Not tight at all in the usual sense, because over-tightening is the most common cause of both leaks and headaches; a hard-pulled strap distorts the skirt and lifts the seal off your face. The strap should sit high on the back of your head and be just firm enough to keep the mask from shifting. If you need it cranked down to stop a leak, the mask does not fit your face.
