Full Face Snorkel Mask Reviews
The Safest Brands & Pros & Cons

The full face snorkel mask is a recent invention that has exploded into a phenomenon full of controversy. This piece of equipment combines a mask and a snorkel into one. The first of this type of mask was the Tribord Easybreath (now Subea), released in 2014. Now there are many other brands.

The controversy around these masks stems from snorkeling deaths potentially linked to them. In particular off-brand masks that may not be properly venting exhaled CO2 gas. At this point no one really knows for sure if there is a correlation between these deaths and full face snorkel masks. But it is worth being very cautious about.

We have now tried a number of these masks, and we still prefer our traditional masks and snorkels. But, we know many veteran snorkelers who love their full face masks. So, as with all equipment, it is a personal preference.

Below you will find our full face snorkel mask reviews with recommended brands and models. And farther down this page make sure to read all the pros and cons of using one of these masks. In the interest of safety, we only recommend masks that have been tested for CO2 buildup. This buildup can happen when exhaled gases are not being properly eliminated, causing people to re-breathe the CO2 they have already exhaled.

A correct fit is critical for safety! With all models and brands we believe  incorrectly fitted masks are partially responsible for CO2 re-breathing problems. Read our fitting safety tip below to learn more.

If you plan to travel with your full face snorkel mask, be aware that some tour companies and liveaboards are not allowing use of them during their excursions. So, check ahead or be prepared with some standard equipment.

What Are the Safe Brands?

Many of the full face snorkel mask products available are inferior knock-offs. Please avoid buying an off-brand full face snorkel mask for your safety. They have leaking issues, fog up, and the dry snorkel often fails, cutting off breathing or flooding the mask, and as stated above they may put your life at risk because of CO2 buildup. That is why we only recommend masks that have been tested for CO2 levels by known manufacturers. There are only a couple of these manufacturers, and we cannot even say for sure that their masks are safe for everyone.

SEAC - Our Top Brand With One Caveat

SEAC built their own mask CO2 testing system to ensure safe levels.

In our experience, the best brand of full face snorkel masks is the Italian company SEAC. They have the breathing figured out. Their masks are, by far, the best breathing of any full face mask we have tried. It is easy to get a full fresh breath of air, which cannot be said for other masks in our experience. On all SEAC models the entire snorkel tube is dedicated to the inhale. Your exhale leaves through separate tubes to purge valves at the top of the mask body, on the back side. And while that is a good feature, it is also the one potential feature some people may not like, because when you dip your head down a bit into the water, and those valves go underwater, it makes breathing out much harder (like when you dunk a dry snorkel). Though there are no regulations or guidelines governing CO2 levels in full face masks, SEAC tests all of their masks to meet European regulations for safe CO2 levels for snorkel tubes & full face dive masks.

SEAC Libera Full Face Snorkel Mask

The SEAC Libera Full Face Snorkel Mask (here on Dolphin) is leaps and bounds better than other masks on the market, if it fits you. Not only are all SEAC's masks the best breathing we have experienced, but the new Libera has addressed nearly every major safety and comfort issue that many full face masks have. The Libera also comes in a child size. And the SEAC Fun is a more affordable child-sized version of the mask with a non-silicone skirt.

Dedicated Inhale Only Snorkel - The entire snorkel tube is for breathing air in. So you get lots of fresh air, and the snorkel itself remains compact, which is nice for packing in luggage (the snorkel is easily removed), and for less resistance to wind and water. In the graphic below fresh air is shown in blue, coming down the snorkel, into the chamber with your eyes, and then it moves through check valves into the chamber below with your nose and mouth.

The inhale comes in through the snorkel and the exhale goes out through valves in the top rear of the SEAC Libera Full Face Snorkel Mask.

Dedicated Exhale Valves in Mask - Your exhale (shown in red above) exits at the top of the mask body through valves - not through the snorkel. This keeps the distance your out-breath has to travel short, making it easier to exhale your CO2 fully. There is a tube on each side of the mask making it very easy to breathe out. Additionally, when you breathe in, these valves close, preventing you from re-breathing expelled air that may be left over in the tubes. But the position of those valves is slightly problematic because when you dip your head down into the water, those valves close, making it much more difficult to breathe out because of the water pressure against the valves. It is something you can get used to though.

Most other full face masks send the exhale out the snorkel in narrow and long separated tubes.

Massively Reduced Internal Air Volume - Take a look at the Libera mask next to a Wildhorn Seaview 180 V2 mask (click to make the picture bigger). Notice how much thinner it is? SEAC has greatly reduced the internal volume of air in the mask. This makes it much easier to circulate fresh air, instead of re-breathing old air. It is more compact for travel. And there is still plenty of room in the mask for big noses. The Wildhorn mask and many others have big spaces in front of your face and nose and mouth area. 

Silicone Mask Strap & Quick Release Buckles - The majority of full face snorkel masks have fabric mask straps. They are hard to tighten, and they make the mask very difficult to remove when you are in trouble. The Libera mask uses very easily adjustable silicone straps. And at the bottom of the mask those straps attach with quick release clips. Just push the round button and the mask comes off quickly and easily. Fabric straps on other masks also stay wet longer.

SEAC Unica Full Face Snorkel Mask

SEAC also has two other masks that we have tried on and found to be good breathing. They use the same dedicated snorkel for incoming breath, and the same separate exhale valves at the top of the mask. They are also fairly low volume masks compared to other brands. But they lack the other advanced features of the Libera above.

The SEAC Unica (here on Dolphin) has a high quality silicone mask skirt, but features the same fabric straps as most other brands. Although it is still tested for safe levels of CO2. For just a little more money we would buy the Libera.

SEAC Magica Full Face Snorkel Mask

If you are looking for an affordable full face snorkel mask that has been tested for safe CO2 levels, with the good breathing characteristics of all the SEAC masks, the SEAC Magica (here on Dolphin) is a good option. To keep costs down the mask uses a thermoplastic skirt instead of silicone (although some websites say it is silicone).

Head/Ocean Reef Full Face Snorkel Masks

If you cannot get a good fit with one of the SEAC masks above, then consider either the Head (Mares) Sea VU Dry (here on Dolphin) or the Ocean Reef Aria, that are essentially the same with a patented design, and are tested for safe CO2 levels. They use the same testing machines as used for diving rebreather full face masks. They have found that the harder you breathe, the less CO2 buildup there is.

In all of these masks the snorkel has three separated tubes contained within it, the center one is for the inhale, and the outside ones are for the exhale. But we did not breathe as easily in the Head/Ocean Reef mask as the SEAC above.

Ocean Reef now has an Aria QR (pictured at right), which has quick release clips on the mask strap, which is the one we would get because of that feature. These masks are made in Italy and come in three sizes, including a child's.

There are accessories for these masks to add a Snorkie Talkie radio communicator, a GoPro camera mount (not a great tool, read more below), a marker wing and an optical lens support.

Full Face Snorkeling Mask Fitting Safety Tip

We believe that incorrectly fitted masks may be contributing to CO2 problems. We have tried on lots of different brands and sizes of full face masks. And we have rarely found a correctly fitting mask, for either of us. We suspect many people are using masks that do not fit correctly. When you breathe out in these masks, the seal above your nose is supposed to prevent exhaled air from escaping back into the chamber above where your incoming air comes in. If, when you breathe out, you feel air blowing up past your nose to your eyes, that is a bad fit. You will then be re-breathing thoses CO2 gases in your next inhale. This can happen with any brand, and is very common in our experience.

Is a Full Face Snorkeling Mask Right for You?

Check out this list of the pros and cons of these masks to help you decide if you want to try one.

Pros & Cons of a Full Face Snorkel Mask

First, the advantages:

Easier for Beginners - No Learning Curve
For beginners a full face snorkel mask can really be a boon. There is no learning curve or getting comfortable breathing through your mouth. You simply put it on and breathe normally.

Even if you are not a beginner, these masks are great if you have issues with sore jaws or mouth from holding onto the snorkel.

Full Face Snorkeling Mask Out of the Water

Less Mask Fogging Problems
Through a system of airflow across the inside of the mask lens, these masks are not as prone to fogging. Though as with any mask, you do need to keep it clean. But do not use toothpaste like we recommend to prevent mask fogging on regular masks, as the lens is plastic and will be scratched. Try dish soap instead.

Large Unobstructed View
All of these masks and many of the reviews remark on the large unobstructed 180° view that they have. We actually find that the masks offer less peripheral vision than our traditional masks, because of the size of the frame on the sides.

Great for Men With Mustaches
For men with mustaches, these masks give you the option to not have to shave it off. With a beard, there will be some leakage though.

Built-in Dry Snorkel
All full face masks we have seen have a dry valve at the top of the snorkel. This means that if a wave comes over you or you submerge the snorkel, it will stop the water from coming in. We recommend these for general snorkeling, so this is a good feature.

Option for Prescription Lenses
There is the option of an optical lens support that can be used inside some full face masks (Ocean Reef Aria, and Head Sea VU Dry for sure), so that you can install your prescription lenses. You must have the lenses installed by your optician. And the glasses frames just basically wedge into the mask skirt, so it is not going to be a perfect fit for everyone.

Now for the disadvantages:

Designed for Casual Snorkeling - Not Exercise
Besides the risks of CO2 buildup mentioned at the top of this page, the majority of full face snorkel masks say they are for casual snorkeling, not exercise. And in our personal experience most masks are difficult to get a full breath of air in even when casually snorkeling. It does seem that re-breathing exhaled breath is an issue. Most manufacturers actually warn that you will not be able to get enough oxygen if you wear one while exercising intensely enough to need to breathe through your mouth. You can find many reviews of people saying they cannot breathe easily, get headaches or are lightheaded, with most masks.

Not for Diving Down - Despite the Pictures & Videos
Yes, every advertisement and video for full face masks shows people diving down. But beyond going down a few feet you really can't safely freedive in a full face snorkel mask. You have no way to equalize the pressure in your ears that quickly increases as you dive down. Equalizing requires you to hold your nose and blow air into your ears. If you don't do this you will damage your ears. And there is no access to your nose in this type of mask. There is a mask called the Ninja Shark Equalizer that does have a flexible nose pocket. But that mask does not solve the other issues that all of these masks have when diving down. They have a lot of volume of air inside the mask. All that air creates a strong pressure on your face as you dive down. This cannot be relieved as it can with a normal mask by breathing out slightly through your nose. So, if you like to freedive down to get a closer look at the reef and creatures, do not purchase one of these masks.

Fabric Straps Can Be a Problem
The fabric straps that come on most full face snorkel masks are both difficult to get tight when putting it on or to loosen when taking off the mask. You need to place a strap holder around the end of the strap in order for it to stay where you have adjusted it to, which is difficult when it is on the back of your head. Then, when you need to get it off, you have to get those strap holders loose in order to get the straps loose and get the mask off your head. It is not quick or easy.

We Find These Masks Very Hot
Something that is very noticeable and uncomfortable for us is that full face snorkel masks are very hot inside. The hot feeling is partly caused by our warm breath in the lower breathing area. But the large window also acts like a greenhouse. We have read other reviews stating similar experiences, even going as far as to recommend that they are only usable in cool water.

Air Across Eyes Is Drying
With these masks your incoming breath comes in at the top of the mask, and is drawn across the mask in front of your eyes, before going through valves into the breathing chamber where your mouth is. This is supposed to help prevent the mask from fogging. But we find the constant airflow across our eyes very drying and irritating.

Lens Is Easily Scratched Plastic
A traditional mask is tempered glass. But full face snorkel masks are plastic and are easily scratched, which mars your view. So, you must be very careful about how you pack, travel and care for your mask. You should not let it get sandy at all. Full face masks will likely not last as long as traditional masks because of this.

Bulky for Travel
Speaking of packing, a full face snorkel mask is a large bulky thing and will prove more challenging to pack for travel than a traditional mask and snorkel, that take up less room. If you have soft sided luggage the plastic mask could easily be broken during transport.

Talking Not Easy Between Snorkelers
You would think that it is easy to talk to your snorkel partner with one of these on, compared to having to take the snorkel out of your mouth. But in our experience people cannot hear you well with the mask on. So, imagine having to remove your entire mask to talk to someone and then putting it back on each time.

GoPro Mounts at Top Not Useful
A number of full face snorkel masks come with a GoPro mount just above the lens, near the top of your forehead. While this sounds like a marvelous idea, it is pretty useless in real life. You can see in the pictures on this page that the top of the mask where the camera is mounted is out of the water, or nearly so. This means that your camera is taking pictures or videos above the water, not under it. Even if you tilt the camera down so that it is in the water, it will be looking at the ocean floor, probably not what you want for your video. Some masks have started placing the camera mount on the side of the mask which is an improvement.

If you are absolutely set on using this option, you can buy an extension that will put the camera basically in front of your mask lens like the photos in this Amazon review. With this option you will likely get some decent video, but your view from inside your mask will be reduced.
