Scores are our editorial opinion of these models, based on features, suitability and ownership trade-offs—not hands-on test results. How we chose →
We’d pick the Frameless 2 Mask.
Our pick is Atomic Aquatics Frameless 2 Mask. Our favourite here for a simple frameless layout with a soft sealing flange. We would start the fitting with this one.
Which one suits you?
Atomic Aquatics Frameless 2 Mask

Our favourite here for a simple frameless layout with a soft sealing flange. We would start the fitting with this one. A softer skirt still needs to match your face; try the available sizes.

We would shortlist Calibro for a close-to-face twin-lens design and the nose-pocket membrane aimed at reducing fog. Fog Stop is a design feature, not a promise that you can skip mask preparation.

What the differences mean when you buy
Lens layout and usable vision
Atomic Aquatics Frameless 2 Mask
- Window layout
- Single window
- Lens
- UltraClear glass
Cressi Calibro Mask
- Window layout
- Twin window
- Lens
- Variant dependent; verify SKU
A single window removes a central lens division, but the view you can actually use also depends on where the glass sits relative to your eyes. Compare downward instrument vision and side vision while wearing the mask normally. Optical options require the exact supported prescription and installation method; a removable lens is not automatically an available corrective lens.
Skirt, frame and nose access
Atomic Aquatics Frameless 2 Mask
- Construction
- Frameless
- Skirt
- Dual-hardness silicone; UltraSoft sealing flange
Cressi Calibro Mask
- Construction
- Integrated dual frame
- Skirt
- Internal Fog Stop membrane
Treat skirt and frame differences as reasons to try the masks, rather than a comfort ranking. Check for pressure around the bridge, brow and upper lip. Repeat the fitting with your regulator mouthpiece and hood because they can change the seal. A low-volume description does not provide a measured clearing advantage, and frameless construction does not guarantee a smaller internal volume.
Straps, buckles and protection
Atomic Aquatics Frameless 2 Mask
- Adjustment
- Squeeze-adjust buckles
Cressi Calibro Mask
- Adjustment
- Buckles on flexible skirt attachments
Try the buckle operation with the gloves you use and check whether a replacement strap is available. An elastic strap, silicone strap and different buckle locations can feel quite different over a hood. Confirm whether a hard case or soft bag is included, then plan storage so the skirt is not compressed by heavier gear.
A closer look at both
Frameless 2 Mask
A single-window frameless mask with a skirt combining two silicone hardnesses and a softer sealing flange. Atomic lists Standard, Medium and Large fits, all with UltraClear glass. The size choice is a practical distinction to investigate in a fitting session rather than a guarantee that one size works for every diver.
What we like
Our favourite here for a simple frameless layout with a soft sealing flange. We would start the fitting with this one.
What would make us think twice
A softer skirt still needs to match your face; try the available sizes.
More about the Frameless 2 Mask →Calibro Mask
Calibro uses Cressi’s integrated dual-frame construction and an internal membrane around the nose pocket marketed as Fog Stop. The design brings the angled lenses close to the face.
What we like
We would shortlist Calibro for a close-to-face twin-lens design and the nose-pocket membrane aimed at reducing fog.
What would make us think twice
Fog Stop is a design feature, not a promise that you can skip mask preparation.
More about the Calibro Mask →Four checks before you place an order
- Try the actual size or fit variant with your normal regulator mouthpiece; reject persistent pressure points.
- Check nose access and instrument vision while looking through the mask at normal angles.
- Operate both strap systems, including loosening them, with the gloves and hood you expect to wear.
- Confirm the exact lens variant, any corrective prescription, replacement strap availability and the return policy before ordering.
Ask for a quote for the complete kit, including the accessories you need. That makes the price comparison much more useful.
Price, accessories and owning the equipment
Price the finished mask, not just the frame. Corrective lenses, fitting, a replacement strap and a protective case can change the total. A model with a cheaper base price may not be cheaper once the required optical setup is included. We do not have a current like-for-like retail quote for this pair, so there is no supported price winner.
For an upgrade, identify what your existing mask fails to do. If it seals comfortably and gives usable vision, a different glass name or new model suffix alone is a weak reason to replace it. Follow the specific manufacturer preparation, cleaning and storage guidance; avoid assuming every lens coating accepts the same treatment.
How we scored these models & further reading
These are our subjective buying scores out of 100. We weigh the usefulness of the features, the intended diving or carrying job, and the compromises involved in owning the gear. They are not laboratory measurements, safety grades or customer averages. The verdict applies to the two named models, not everything either brand makes.
90–100: one of our first choices for the stated job. 80–89: a strong option with trade-offs. 70–79: a more specific fit. A different fit, camera, valve or dive plan can change which one you should buy.

Product details and further reading →Questions worth settling
Does either mask make deeper diving safer?
No mask in this comparison establishes a safe diving depth or replaces training. The buying questions remain fit, usable vision and access to the nose pocket. Manufacturer construction claims and a published product score do not demonstrate suitability for a particular technical dive.
Which is the better buy for this particular comparison?
A softer skirt still needs to match your face; try the available sizes. We would shortlist Calibro for a close-to-face twin-lens design and the nose-pocket membrane aimed at reducing fog.
Our pick is where we would start. Choose the other model if its fit or features better match your setup—especially where a camera, valve, boot or exposure suit needs an exact match.
