Dive Mask Buying Guide | How to Choose the Perfect Mask
A scuba mask might look like one of the simplest pieces of dive equipment, but choosing the right one can make an enormous difference to your comfort underwater.
A poorly fitting mask can leak, fog, create uncomfortable pressure points and distract you throughout your dive. A well-fitting mask can almost disappear once you’re underwater.
Unlike many pieces of scuba equipment, the best dive mask isn’t necessarily the most expensive one. It’s the one that fits your face correctly.
At Oceans Unlimited Costa Rica, we help new and experienced divers find masks for recreational diving, professional diving, travel and underwater photography. This guide explains what to look for when buying a scuba mask and how to find the right fit.
What Makes a Good Scuba Diving Mask?
A good dive mask should:
- Create a comfortable watertight seal
- Provide a clear field of vision
- Have tempered-glass lenses
- Sit comfortably against your face
- Be easy to equalize while descending
- Have an adjustable, reliable strap
- Suit the type of diving you do
Features and appearance matter, but fit should always come first.
A $200 mask that doesn’t fit your face is a worse choice than a $70 mask that fits perfectly.


Scuba Masks vs Snorkeling Masks
Although they may look similar, a mask intended for scuba diving needs to cope with increasing pressure as you descend.
A quality scuba mask will typically feature:
- Tempered-glass lenses
- A soft silicone skirt
- An enclosed nose pocket
- Strong buckles and strap attachments
- A relatively low internal air volume
The nose pocket is particularly important because it allows you to equalize the pressure inside your mask as you descend and pinch your nose when equalizing your ears.
When purchasing a mask specifically for scuba diving, choose one designed and rated for that purpose rather than simply selecting a general swimming or snorkeling mask.
For a new diver, simplicity and readability are often more valuable than having dozens of advanced features.
The Most Important Factor: Mask Fit
If you remember one thing from this guide, make it this:
Buy your mask based on fit first and features second.
Everyone’s face is slightly different. The width of your face, shape of your cheekbones, distance between your nose and upper lip and even the shape around your temples can affect how a mask seals.
This is why a mask your dive buddy loves might leak constantly on you.


How Should a Scuba Mask Fit?
The silicone skirt should make even contact around your face without sitting on your hairline or interfering with your upper lip.
To perform a basic fit check:
- Move any hair away from your face.
- Place the mask gently against your face without putting the strap around your head.
- Tip your head back
- Get a friend to look at the seal all around the mask skirt
You’re looking for an even seal.
However, don’t rely solely on the traditional “inhale and see if it sticks” test. Many masks can temporarily stick to your face when you inhale strongly enough.
Instead, pay attention to where the skirt sits and whether you can feel obvious gaps or pressure points.
Don’t Overtighten Your Mask
A surprisingly common mistake is wearing the mask strap too tightly.
Your mask doesn’t need to be clamped onto your face.
Underwater pressure actually helps hold the mask against you. The strap primarily keeps it correctly positioned.
Overtightening can:
- Distort the silicone skirt
- Cause leaks
- Create uncomfortable pressure
- Leave marks around your face
- Cause headaches during longer dives
The strap should be secure but comfortable.


What Is a Low-Volume Dive Mask?
The “volume” of a mask refers to the amount of air space between your face and the lenses.
A low-volume mask places the lenses closer to your eyes.
This provides several advantages:
- Wider field of vision
- Less air required to equalize the mask
- Easier mask clearing
- More compact design
- Excellent visibility
Low-volume masks are extremely popular with recreational divers, freedivers and underwater photographers.
For most divers, a low- or medium-volume mask is an excellent choice.
Single-Lens vs Dual-Lens Masks
One of the biggest design choices is the lens configuration.
Single-Lens Masks
A single-lens mask uses one continuous front lens, although the nose pocket still sits beneath it.
Advantages
- Open feeling
- Excellent forward visibility
- Uninterrupted central field of view
- Simple design
Divers who dislike feeling enclosed often enjoy single-lens masks.
Dual-Lens Masks
Dual-lens masks use separate lenses for each eye.
Advantages
- Often very low volume
- Compact design
- Excellent field of vision
- Prescription lenses may be available
- Wide range of styles
Neither design is inherently better.
The choice mostly comes down to fit, vision and personal preference.

Frameless vs Framed Dive Masks
Another important choice is whether to buy a traditional framed mask or a frameless design.
Framed Masks
Traditional masks have a rigid frame surrounding the lenses.
Advantages
- Strong structure
- Wide variety of designs
- Often available with prescription lenses
- Easy-to-adjust buckle systems
- Proven, durable construction
Frameless Masks
With a frameless mask, the silicone skirt is bonded directly around the lens rather than being held inside a separate rigid frame.
Advantages
- Lightweight
- Low profile
- Flexible
- Compact for travel
- Easy to pack as a backup mask
Frameless masks have become extremely popular with travelling divers and dive professionals.
Because they fold relatively flat, they’re also excellent backup masks.
Clear Silicone vs Black Silicone
You’ll notice that many masks are available with either clear or black silicone skirts.
There isn’t a “correct” choice, but they feel noticeably different underwater.
Clear Silicone
Clear skirts allow additional light into the mask.
This can create a brighter and more open feeling.
They’re popular with:
- New divers
- Divers who dislike feeling enclosed
- Recreational divers
The downside is that clear silicone can discolor over time, particularly with heavy exposure to sunlight.
Black Silicone
Black skirts block peripheral light.
This can make it easier to concentrate on what you’re looking at directly through the lenses.
They’re especially popular with:
- Dive professionals
- Underwater photographers
- Technical divers
- Frequent divers
Photographers often prefer black silicone because it reduces distracting reflections and peripheral light.
Ultimately, this is largely personal preference.

What About Colored Silicone?
Many modern masks are available in a huge range of colors.
There is nothing wrong with choosing your mask partly because you like how it looks.
In fact, distinctive equipment can make it easier for your buddy or dive group to recognize you underwater.
Just remember:
Choose the mask that fits first. Then choose your favorite color.
Clear, Tinted and Corrective Lenses
Standard clear lenses are ideal for most divers, but other options are available.
Tinted or Enhanced-Color Lenses
Some manufacturers offer lenses designed to alter contrast or reduce glare.
These can be useful in certain conditions, but remember that any tint changes how colors and available light appear underwater.
For general recreational diving, a high-quality clear lens remains an excellent choice.

Mask Buckles and Straps
The buckle system might seem like a minor feature until you’re adjusting your mask on a moving boat.
Look for buckles that are:
- Easy to adjust
- Easy to operate with wet hands
- Secure
- Durable
- Positioned comfortably
Many modern masks attach the buckle directly to the silicone skirt, allowing the mask to fold flatter for travel.
Silicone Mask Strap or Neoprene Strap Cover?
Traditional silicone straps work perfectly well, but divers with longer hair often find that silicone catches or pulls their hair.
A neoprene strap cover can make the mask:
- More comfortable
- Easier to put on
- Easier to remove
- Less likely to tangle in hair
They’re inexpensive and one of our favorite simple mask upgrades.
Why Does My New Dive Mask Fog?
New masks frequently fog because residue from the manufacturing process can remain on the inside of the lens.
Before using a new mask, follow the manufacturer’s recommended preparation and cleaning instructions.
Once prepared, using a suitable mask defog product before diving can help keep the lenses clear.
Avoid touching the inside of the lenses unnecessarily, as oils from your fingers can contribute to fogging.

What Is the Best Dive Mask for Underwater Photography?
Underwater photographers often prefer:
- Low-volume masks
- Black silicone skirts
- Wide fields of vision
- Minimal reflections
- Comfortable fit for long dives
Black silicone can be particularly useful because it helps block distracting peripheral light while you’re concentrating on a camera viewfinder or screen.
Fit remains the most important factor.
What Is the Best Dive Mask for Travel?
Masks are already relatively lightweight, but frameless models are especially convenient for travel.
Look for:
- Frameless or compact construction
- Low volume
- Soft silicone
- Durable lenses
- Compact storage case
Your mask is also one piece of equipment we recommend keeping in your carry-on luggage when possible.
A well-fitting mask can be difficult to replace quickly if your checked luggage is delayed.
Should I Carry a Backup Mask?
For most recreational dives, a backup mask isn’t essential.
However, carrying one can be extremely useful for:
- Dive professionals
- Technical divers
- Photographers
- Remote diving
- Liveaboard trips
A compact frameless mask can fold into a BCD pocket and makes an excellent backup.
Dive professionals who rely on their equipment every day may particularly appreciate having a spare available.


How Much Should I Spend on a Scuba Mask?
Price shouldn’t be the first consideration when choosing a mask.
A more expensive mask doesn’t automatically fit better.
Instead, prioritise:
- Fit
- Comfort
- Lens quality
- Field of vision
- Build quality
- Features
- Appearance
- Price
A relatively simple mask that fits your face perfectly can be one of the best equipment purchases you ever make.
Choosing a Mask for a New Diver
If you’re buying your first mask, keep things simple.
Focus on:
- Fit
- Comfort
- Clear lenses
- Good visibility
- Soft silicone
- Easy adjustment
You don’t need the most advanced or expensive mask available.
You need a mask you can put on and almost forget you’re wearing.
Our Dive Mask Buying Checklist
Before buying your mask, ask:
- Does the skirt seal evenly around my face?
- Is it comfortable around my nose and upper lip?
- Can I easily pinch my nose to equalize?
- Is my field of vision good?
- Do I prefer single or dual lenses?
- Do I want framed or frameless?
- Clear or black silicone?
- Do I need prescription lenses?
- Is the buckle easy to adjust?
- Will I travel frequently with it?
- Can I comfortably wear it for an entire dive?
If the mask passes those tests, you’ve probably found a strong candidate.
