Freediving Mask Reviews


A well-designed freediving mask allows for effortless equalization of pressure and does fit well besides being leak-proof.

It should also support the fitting of corrective lenses for divers who have focusing defects. The following are the 5 best freediving masks in the market in 2021.

1. EDITOR’S CHOICE: Oceanways Superview-HD Freediving Mask

The Oceanways Superview is a high-definition single lens diving mask that uses optical multi-coating (OMC) technology to minimize glare and ultraviolet rays.

This field-tested underwater diving equipment, manufactured by SeaDive, permits almost complete light passage which allows for objects to be defined even at very low depths.

This allows the diver to explore the underwater scenery without any form of extreme vision distortion hence making their diving experience memorable.

The mask measures 8.6 x 4.5 x 4.4 inches and weighs less than 2 pounds. Its skirt and frame are usually black in color.

The OMC technology complements the design of the faceplate and both operate in sync to reduce the wavelength of light that reaches the eyes of the diver.

This reduction eases eye strain, thus improving eye comfort. Likewise, the OMC technology converts blinding white light into bluish light thereby improving contrast. This also gives it anti-reflective properties.

This freediving mask incorporates TrueColor lenses which are purposely built to provide superb depth perception. The TrueColor lenses can pick up red and yellow at distances of 10 and 20 feet respectively.

The hydrophobic lens prevents the formation of fog during diving. Fog forms when the water vapor from the exhaled breath of the diver condenses into tiny water droplets inside the mask thus reducing visibility.

Another benefit of this mask is that surface grit cannot accumulate on its faceplate, and this allows the diver to move around the seabed, for instance during spear or pole fishing, without losing vision clarity.

The silicone skirt of this mask is fitted to the rigid teardrop-shaped frame. The design of the entire mask gives it a low internal volume.

This low internal volume allows the lens to be located close to the eyes thereby maximizing the field of view of the diver.

Moreover, the strap is designed to fit well around the head of the diver, thus improving the degree of water-seal of the diving mask.

This also makes the process of equalizing the pressure to be pretty effortless, and the diver rarely experiences mask squeeze, except only when the mask is improperly worn.

Pros of the Oceanways Superview-HD Freediving Mask
  • Low volume.
  • Superb design.
  • Effective water seal.
  • Decent vision.
  • Effortless equalizing of pressures.
  • Can be used by amateur divers.
  • Vision brightening lens.
The Cons
  • Opaque skirt reduces peripheral vision.


The superb design, powerful functionality, and field-tested efficiency of Oceanways Superview-HD along with its anti-UV, anti-glare, and anti-fog features make it ideal for both freediving and scuba diving, as well as a for spearfishing.

These unparalleled features also make it the best freediving mask on the market in 2021.

2. BEST BUDGET: Cressi Scuba-Diving Mask with Snorkel Set

The Cressi scuba-diving mask comes with a snorkel set which allows it to be used safely by both adults and children. This frameless mask is manufactured by Cressi, and it features a flex tub and a soft silicone mouthpiece.

It weighs about one pound and measures 8.03 inches in length and 2.68 inches wide. Its height when the snorkel set has been fitted is approximately 16.14 inches. Its lack of frame allows users to fold it and fit it into backpacks.

Its sleek design features a liquid silicone skirt which is directly attached to the lens. This gives an extremely low internal volume, even when compared to Oceanways Superview.

This also allows the glass lens to be placed very near the eyes of the diver. Likewise, the frame-less skirt can be easily swiveled, hence increasing the field of view of the diver.

In fact, its field of view is greater than that of Oceanways Superview. Even so, its lens does not compare to the one used in Oceanways Superview.

The lens is made from tempered glass which reduces reflections inside the mask. This anti-reflective feature allows objects to be seen clearly. However, its degree of depth perception is quite lower than that of Oceanways Superview.

The snorkel set used is the desert dry variant which can function optimally even when the diver has been submerged in water. If this submersible snorkel set is fitted properly, water leakage cannot occur. This has led it to be described as a dry snorkel.

This mask also incorporates a dry-top feature which serves to prevent water from leaking into the mask from the hair.

Generally, when any freediving mask is fitted over hair, there cannot be an effective seal as water can drain down the hairs into the mask.

The dry top feature allows the diver to fit the mask just below the hairline, and if this is not possible, to push the hair away from the mask. This ultimately prevents water from draining down the hair into the mask.

One key detriment of this mask is fogging. The nose pocket is well-placed to allow exhaled air to equalize the pressure in the mask with the outside ambient pressure.

However, it also allows water vapor contained in the exhaled air to create a fog inside the mask hence limiting visibility.

Pros of the Cressi Scuba-Diving Mask with Snorkel Set
  • Very Low volume.
  • Frame-less design.
  • Decent vision.
  • Effortless equalizing of pressures.
  • Can be used by amateur divers.
The Cons
  • Fogging.
  • Opaque skirt reduces peripheral vision.


The Cressi scuba-diving mask is a light-weight well-designed freediving mask that features a snorkel set and has an incredibly wide field of vision which makes it ideal for snorkeling, freediving, scuba diving, and ocean photography.

3. SPORASUB Mystic Freediving Mask

The SPORASUB Mystic Mask is an ultra-low volume freediving mask that features a universal fit. It is designed and built by Omer.

This diving mask consists of two key components; a polycarbonate frame and a silicone skirt. It measures 8 inches in length, and its width is 4 inches. Its height is about 4 inches. It weighs less than 2 pounds. The color of its frame and skirt is black.

The frame holds two lenses. The matt finish of the frame and skirt reduces their ability to reflect light.

Lens rings are not used in this mask, as the lens is attached directly to the frame. This reduces the overall internal volume, as well as increases the visual field of the diver. The protruding strap allows the frame to fit well on the face.

Its design also reduces the internal volume. In fact, its internal volume is about four-fifths the internal volume of its close variant, the Omer Alien. This ultra-low internal volume makes the pressure-equalizing process effortless, as well as increases the field-of-view.

Acetylic resin is used to construct the buckles. This makes the buckles flexible, as well as allows them to handle traction well.

Likewise, the buckles also allow the diver to reposition the mask while submerged without interfering with the water seal.

Its front panel is molded into the mask, but it can still be disassembled. This allows the diver to replace the lens with a more appropriate prescription lens.

Therefore, it can be used with divers who suffer from focusing defects. Regardless, the process of replacing the lenses must be done properly or else a poorly fitting lens can allow water to leak into the lens.

Also, like Cress Nano, the SPORASUB Mystic Mask still suffers from fogging. This is due to exhaled water vapor accumulating inside the mask and condensing as very tiny water droplets.

Even so, there are special liquids that divers can apply to the lenses that will prevent water droplets from condensing on top of them.

These special liquids coat the interior surface of the lens with a liquid film, and when condensing water vapor comes in touch with this film, it simply drains off hence minimizing fogging.

Pros of the SPORASUB Mystic Mask
  • Replaceable lenses.
  • Universal fit.
  • Decent vision.
  • Effortless equalizing of pressures.
The Cons
  • Fogging.


The SPORASUB Mystic Mask is a lightweight, ultra-low volume freediving mask whose design features allows for a universal fit, and can thus be used by adults, and teenagers.

4. Scubapro Steel Pro Freediving Mask

The ScubaPro Steel Pro is an ultra-low volume, single lens freediving mask designed to offer a watertight seal. It is designed and made by ScubaPro.

It measures 8.43 inches in length, and its width is 4 inches. Its height is about 4.41 inches. It weighs about 0.8 pounds.

It is designed to offer comfortable wear to divers for extended periods of time. This makes it suitable for divers engaging in ocean exploration or underwater photography.

Its skirt is made of supple silicone, and this makes it flexible enough to fit onto all face shapes while retaining its watertight seal.

The double-feathered edge of the skirt ensures that the mask fits tightly on the face, and this prevents water leakage. It does not have a frame, and this enables it to fit close to the eyes hence reducing the internal volume.

The shape and angulation of the faceplate allow the mask to fit closely to the eyes hence allowing the diver to have a wider visual field.

Also, the lens placement enhances peripheral vision. Collectively, these give this diving mask an exceptional field-of-view.

The lens is made from clear scratch-resistant glass. This allows them to be used for a long time without the diver experienced distorted visions. Likewise, grit cannot accumulate on the lenses.

The buckles feature an adjustable strap. This strap allows the buckle to be rotated or repositioned without breaking the water-seal. It is comfortable to wear.

Its ultra-low volume offers one key benefit; it reduces the amount of air required for pressure equalization. This has an added benefit of reducing the amount of exhaled air that is trapped inside the mask, and this ultimately reduces the probability of fog forming in the mask.

Its head strap has a wide split which allows for easy adjustment. Moreover, it allows the nose pocket to have access to the ear pocket.

Thus, the exhaled air is also used to restore the pressure equilibrium in the ear pocket. This is quite useful as this pressure equilibrium allows the diver to stand and walk around the ocean bed without falling. Thus, this mask is suitable for underwater exploration of sites.

Pros of the ScubaPro Steel Pro
  • Ultra-Low volume.
  • Frame-less design.
  • Decent vision.
  • Good water seal.
  • Effortless pressure equalization.
The Cons
  • Depth perception of lens is low.


ScubaPro Steel Pro is a low-weight, frame-less, single lens freediving mask, whose ultra-low volume design allows for effortless pressure equalization and creation of a persistent watertight seal.

5. The Cressi NANO freediving mask

The Cressi NANO is a diving mask purposely built for spearfishing and advanced freediving. Its hydrodynamic shape reduces drag, hence improve its efficiency. It is designed and made in Italy.

It weighs about 0.7 pounds and measures 9 inches in length and has a width of 4 inches. Its height is 4 inches. The color of its skirt and frame is black.

Its frame features a strengthened and well-thinned nose bridge. This reduces the amount of contact that the frame makes with the nose bridge of the diver, hence reducing the discomfort associated with frame-nose bridge contact. In fact, this gives it better nose wear than the Oceanways Superview-HD mask.

The nose bridge also partitions the faceplate into two separate windows. Each of the angles of the windows rakes towards the cheekbone hence allowing them to closely fit near the eyes.

This also allows the lens to be close to the eyes of the diver, hence increasing the field of view, as well as increasing the degree of peripheral vision. Its peripheral vision is much better than that offered by either Oceanways Superview or Cressi scuba-diving mask.

The shape of its lens can best be described as a reverse teardrop. This shape, along with the low internal volume, allows the diver to have an exceedingly broad field of view as well as reduces the visibility of the frames.

The field of view of Cressi Nano is almost the same as that of Cressi scuba-diving mask.

The skirt is made from pure silicone, and this makes it flexible enough to reduce the internal volume as well as allow the lens to be placed near the eyes. It also allows the frame to have a raked angle.

The buckle system that is designed to securely fit the mask around the head of the diver is quite flexible and almost indestructible.

Its flexibility creates a secure fit that prevents the mask from dislodging when the diver encounters ocean currents while swimming close to the ocean bed.

Likewise, the flexible rubber on the buckle system allows the diver to reposition the mask without losing the water seal.

Like other free-diving masks that have a low internal volume, the equalizing process is quite effortless.

This, when combined with the hydrodynamic design of the mask, allows divers to smoothly cut-through-water, as well as aids their movements when they are swimming inside enclosed spaces.

Even so, the lens used in this mask cannot match with that used in Oceanways Superview.

However, the two lenses of Cressi NANO have similar properties as those used in the Cressi Scuba-diving mask. Fogging can occur during use.

Pros of the Cressi NANO
  • Hydrodynamic design.
  • Secure fit.
  • Decent vision.
  • Effortless equalizing of pressures.
The Cons
  • Not suitable for amateurs.
  • Fogging


Cressi Nano is a light-weight, twin-lens frame diving mask featuring a sleek design that allows for an incredibly wide field of vision which makes it ideal for spearfishing and advanced freediving.

Buying a Freediving Mask – A short OC Guide

It goes without saying that a good freediving mask is very important if you want to fully enjoy everything this exciting sport has to offer.

From providing excellent (fog-free) visibility to fitting correctly and being comfortable, there are a number of issues you should think about when buying a new diving mask.

Let’s take a look at some of those now.

Low Volume, please

A low volume mask essentially means less air can be trapped inside. This is an important consideration because in practice you do not need to waste so much air from your lungs in order to equalize the mask or clear water from it.

Freediving masks have nose pockets that allow you to do this. As you descend and the pressure outside the mask begins to squeeze in on your face, a short exhale through your nose will help circulate air into the mask space and thus equalize the pressure.

In fact, some modern freediving mask designs have such low volume they do not require you to actively equalize. 

Fits like a glove (shaped like a mask)

An obvious requirement for a good dive mask is the ability to fit your head and face. You should lookout for a soft silicon skirt surrounding the edge of the mask. This will help improve the seal against your face.

Lower quality masks with PVC based seals are best avoided as they are less efficient and can be uncomfortable.

If you’re freediving with a mask that doesn’t fit properly you will end up frustrated.

However, even a mask with a glove-like fit needs to be worn correctly. Below are a few pointers on getting the right fit.

How to wear a freediving mask the right way:

How to wear a freediving mask the right way:

  • Place the mask onto your face and shift the position until it is centered and the seal is comfortably true against your skin.
  • Then, gently suck air through your nose so that the mask clings to your face. If the seal is good the mask should remain against your face for a few seconds unaided.
  • Find the same position on your face and adjust the strap so that the mask holds its position.
  • Suck a small amount of air as in step 2. The seal should fit comfortably against your skin and the strap should not be too tight.
  • With the mask comfortable seal you are ready to dive.

Single or double pane lens

Dive masks vary in that some will come with 2 panes of glass (double pane) or a single pane.

This one is actually down to a personal choice on what you find most comfortable to look through and wear.

From a performance perspective, there is no real difference. You should, however, look out for tempered glass as this is more durable.

An anti-reflective coating is another good addition to the glass as this will help prevent glare.

Color of the seal and lens

Some freediving masks opt for outlandish color schemes. This type is best avoided.

A colorful or light-colored seal will actually allow more light into the mask. At the wrong angles, this light can reflect and bounce on the inside of your mask and cause unwanted reflections and glare.

This is why a black or colored opaque skirt and seal works better. The outside light is blocked from entering your mask at the side, therefore minimizing the chance of glare.

Colored or reflective lenses are another aspect that really does come down to personal preference. In very sunny environments a reflective lens will increase your visibility. However, for spearfishing, a reflective lens will be counterproductive as you may well end up giving your position away.

Another potential negative of colored and reflective lenses is that your dive partner is unable to see your eyes.

If you are in trouble, your eyes convey a lot of information, (they can show signs of hypoxia for instance). You should ask yourself whether you are comfortable losing this line of communication.

Plastic Lenses

We mentioned above that tempered glass is the lens material to go for. However, these days clear plastic lenses are proving popular with freedivers.

The reason is due to the fact masks with plastic lenses can bend under pressure. The flexibility of the lenses means the mask can bend against the face providing an even greater seal, without the uncomfortable impact of ask squeeze.

Masks with plastic lenses can also bend around your face, giving you a much wider field of vision; (although the edges of that field of view will be distorted due to curvature).

The Aquasphere Sphera is one of the best plastic lens masks currently available. You can view more on that here.

Straps & Fastening

A quality mask will have a simple yet effective strap mechanism that will allow you to adjust the strap quickly and easily.

You do not want a mask that requires you to remove it from your face every time you need to adjust it slightly.

If you are not in a position to test the strap before you buy, (due to making a purchase online for instance), pay close attention to images available as this will help you ascertain the type of strap and fasten system the mask employs.

Customer comments and reviews are also good at revealing any issues people might have had getting the mask to fit comfortably and securely.

Longevity – a mask to last

Finally, you will want a mask that will stand the test of time. This very often depends on the quality of the manufacturer and the materials used for construction.

For instance, plastic lens masks have the high performing aspect of being able to bend and contort, however, they are not as strong as tempered glass.

A silicon seal should last longer than a PVC one. There is also the issue of looking after your mask. Look out for brands that supply a sturdy case with the mask so you can safely pack it away when not in use.

You should also rinse the mask in fresh water after diving and allow it to dry fully before putting it in the box. Simple care and attention will help make your mask last longer, no matter what type you buy.
