Atomic Aquatics Frameless Mask

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.

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.

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.

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.

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.

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.

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.

The Medium (M) fit is the smaller of the two and is intended for smaller faces, while REG (Regular) is the standard size. Both share the same frameless design, UltraClear optical glass lens and squeeze-to-adjust buckles. Regular is listed here in Black and Clear silicone, and Medium is listed in Black, Clear and the co-molded color accent combinations.

The skirt is available in clear or black silicone rubber with co-molded color accents. Listed options are Black, Black/Pink, Black/Purple, Black/Fuchsia, Clear, Clear/Pink, Clear/Purple and Clear/Fuchsia. The skirt is offered in clear or black silicone rubber with co-molded color accents, so you can pick either look.

It has no exposed external frame, giving a low volume interior for easier equalizing and hydrodynamic styling with reduced drag.

Yes. The Frameless Mask uses squeeze-to-adjust buckles that allow quick, precise fit changes, even underwater. That makes it easy to loosen a strap that was pulled too tight at the surface or snug things up slightly after the mask settles on your face.
