FAQ

Every Nix Dive Mask is made from a 3D scan of your face to ensure a leak-free seal — even for people with unique facial features like deep temples, surgical scars, muscular atrophy, or face shapes that standard masks rarely fit well. Lenses sit closer to your eyes than on typical masks, which improves field of view and reduces peripheral distortion (especially with prescription lenses). If the first version doesn’t fit perfectly, I’ll revise the design until it does — no extra cost.

Start by ordering a custom mask. After checkout, you will receive an email with a personal link to upload your 3D face scan. All you need is a smartphone or camera. Follow the guide in that email and try to keep your head still and eyes fixed on a distant spot while recording.

Yes — that is the main reason to go custom. Standard masks are built around a few average face shapes. Because each Nix mask skirt is molded from your scan, we can fit narrow faces, wide faces, and a wide range of facial structures that off-the-shelf masks struggle with. If you have had trouble finding any mask that seals, a custom scan is usually the most reliable path.

Often yes, but facial hair can make any mask harder to seal. There are scanning and fitting tips for mustache wearers on the site — check the upload instructions when you order. If the first skirt does not seal the way you need, we can revise the design as part of the fit guarantee.

Yes — including astigmatism, bifocals, and progressives. Upload the prescription from your optometrist; no need to convert it unless you have been told you need prism or other special corrections. Lenses are built into the mask from the start (not glued in afterward), and the optics are tuned for curved lenses close to the eye and for viewing through both air (inside) and water (outside).

Most prescription dive masks use flat or stock curved inserts far from your eyes, which adds distortion — especially at the edges of your vision. Nix lenses are smaller, sit much closer to your corneas, and are calculated for the actual mask geometry and water interface. The result is a wider, clearer field of view and a more natural prescription experience than typical aftermarket lens solutions.

We are currently targeting about 3 weeks turnaround from scan submission to shipped mask. Once our in-house metal 3D printer is online, we expect that to drop to about 4 business days. If you need prescription dive lenses on an even shorter timeline today, services such as See The Sea RX can often turn around glued-in lens work faster while you wait for a custom Nix mask.

All lenses are optically clear but vary in durability:

• Optical Grade Acrylic: Lightweight, optically clear, impact-resistant, less scratch-resistant than glass.
• Tempered Glass: Scratch-resistant and durable, but heavier.
• Sapphire: Extremely hard and highly scratch-resistant — great for rough use or heavy-duty diving.

Yes. All lenses block UV rays and harmful parts of the sunlight spectrum — think of them as sunscreen for your eyes.

• Aluminum: Lightweight, corrosion-resistant.
• Titanium: Ultra corrosion-resistant, hypoallergenic — best for saltwater exposure or sensitive skin.
• Cobalt Chromium: Strong, durable, good for progressive lenses.

No, the aluminum is corrosion resistant. However, titanium offers even better resistance to saltwater corrosion, and the cobalt chromium alloy provides the best corrosion resistance.

Each skirt is produced from a one-off mold generated from your face scan. The skirt is injection-molded in soft silicone so it matches your contours instead of relying on a generic skirt shape. We also shape the skirt with a slight cup so it has gentle preload against your face when you breathe in through your nose — that helps maintain a seal underwater.

Minor cosmetic marks from injection molding can appear and are normal. They do not affect the structure of the skirt or how the mask functions. If you have a fit or leak issue, we address that through redesign — not because of surface texture alone.

The skirt can look bigger in photos because the lenses are smaller and sit much closer to your face than on a typical mask. That lens position is intentional: it improves field of view and reduces edge distortion. Most off-the-shelf masks also ride higher on the forehead than a Nix mask optimized for your geometry.

Pricing is available here: Custom Dive Mask Product Page. Prescription lenses, specialty materials, and extra design work may increase the cost. Pre-order pricing may be available — email if you are ordering ahead of production slots.

We are currently targeting about 3 weeks from scan submission to shipped mask. Once our in-house metal 3D printer is online, we expect that to drop to about 4 business days. Custom manufacture takes longer than buying an off-the-shelf mask, but the goal is a fit and vision experience you cannot get from catalog sizing. If we need to revise the design, it may take a bit longer.

No worries — I’ll redesign and remake it until you get a comfortable, leak-free fit. That’s part of the guarantee.

Nix Dive Mask is based in Vancouver, British Columbia, Canada. We ship internationally, including to the United States, UK, Europe, and elsewhere. Shipping cost depends on destination and service level at checkout.

Yes — the main differences are lens diameter and internal volume:

• Freediving masks use smaller, lower-volume lenses placed very close to your eyes to minimize air space and equalization effort.
• Scuba masks use a larger lens platform and field of view suited to recreational and technical diving.

Because the skirt is custom to your face, freediving masks can achieve lower effective volume than stock low-volume designs built for an average face.

Volume depends on your face, but the combination of a face-matched skirt and lenses placed well under a centimeter from the cornea targets among the lowest practical volumes for your anatomy. If minimizing mask volume is your priority, mention that when you order and we can bias the design accordingly.

Yes — a GoPro mount is available as an order option today. Select the GoPro mount when you configure your mask on the custom scuba mask product page.

Yes. Frame finishes and silicone skirt colors can often be customized. If you have a specific color in mind (for example a bright accent skirt), mention it when you order or contact us before scan upload.

Our upload flow walks you through face capture with a smartphone or camera. Many customers also use photogrammetry apps such as Kiri Engine to produce a 3D mesh; we can work from a quality face scan as long as coverage and scale are sufficient.

If anything in the instructions is unclear, email us — good scan data is the foundation of a good mask.

Your scan is used to model your mask skirt, frame fit, and (if ordered) prescription lens placement. It is not shared publicly. If you have specific data-retention or deletion requests, contact us and we will accommodate them where possible.
