Easybreath FAQ

Have you just bought an Easybreath snorkelling mask? Or are you looking to get one? This should answer most of the frequently asked questions we get! This FAQ section was created thanks to the feedback of Easybreath users. If there’s something you’d like to know and you can’t find it here or on the product page, please leave a comment or send an email to contact.australia@decathlon.com

1. What precautions should I take with my Easybreath?

The biggest thing to look out for: sand.

  • As with sunglasses, avoid letting your Easybreath come into contact with sand. Sand will scratch the window of your mask.
  • If sand is present, do not use force to clip the snorkel into place. Rinse the snorkel and mask before connecting them.
  • Sand can also clog the float valve inside the snorkel. Rinse the snorkel vigorously or use a key that you can fit through the rear vents of the snorkel to unblock the float valve and rinse the snorkel to completely remove the sand.

In order to enjoy the benefits of your Easybreath in the long term, wash it by hand with dish soap after each week of use and store it in its ventilated mesh bag.

2. Why are there three sizes?

The Easybreath is currently available in 3 adult sizes which cover 90% of men’s and women’s faces throughout the world (European, Asian, etc.):

  • the small size adult mask, generally for women and teenagers: S/M
  • the medium size adult mask : M/L
  • the large size adult mask, generally for men: L/XL

3. What size Easybreath should I choose?

The best thing is to try on a mask in your nearest Decathlon store. Once the mask has been tightened to fit against your face, it is the right size if there is no gap between your chin and the silicone skirt of the mask.


If you cannot get to a store or you would rather order your Easybreath on the internet (www.decathlon.com.au), here is how to choose the right size at home:

With your mouth closed, measure the distance between the bridge of your nose and the bottom of your chin:

  • If it measures less than 10 cm (3,9″), choose size X/S
  • If it measures between 10 cm (3,9″) and 12 cm (4 3/4″), choose size S/M
  • If it measures between 12 cm (4 3/4″) and 13 cm (5,1″), choose size M/L
  • If it measures more than 13 cm (5,1″), choose size L/XL

When you receive your Easybreath, put it on to check that there is no gap between the bottom of the mask and your chin. (please see video above)

4. My Easybreath lets in water

There are several reasons why water may be getting into the mask:

  • The most common is due to choosing the wrong size. The Easybreath comes in three sizes for adults. S/M for slim faces, M/L for medium face and L/XL for wider faces. Take a look at the section above on how to choose the right size
  • Warning gentlemen, your beard may be responsible for letting in water. Beards stop the seal between the silicone skirt of the mask and your skin from being properly established.
  • For those with long hair, be careful not to trap any hair between your forehead and the mask.

5. The float valve in the snorkel is stuck, what should I do?

To enjoy using your Easybreath for as long as possible, avoid putting it in the sand. If the float valve is stuck, it is most likely because sand has got between the float and the snorkel wall or salt water has dried and caused it to become stuck.

Use a key that you can fit through the rear vents of the snorkel to move and unblock the float valve and rinse the snorkel to completely remove any sand or salt or dust. Here’s a video with some demonstrations on how to care for your mask.

6. Why is my breathing sometimes blocked?

If the air supply is blocked it’s normally because you have tilted your head too far forward or because a wave has passed over your head. The Easybreath dry top stop water system is at work preventing water from getting inside. Your snorkel must have been totally submerged, therefore the float went up to plug the hole.

If you had leaned your head too far forward with a traditional snorkel you would have been breathing in water.

All of our testers were surprised the first time too. 🙂

7. How do I clip on the Easybreath snorkel?

If you are having difficulty clipping the snorkel onto the mask, this is usually because there is sand or salt where the two parts connect, near the seal or in the snorkel. This connection is precise to the nearest millimetre to ensure a perfect watertight seal between the snorkel and the mask.

If sand is present, do not use force to clip the snorkel into place. Rinse the snorkel and mask and make sure that there is no more sand left before trying to connect them again.

8. Why is there a buzzing sound when I breathe in?

To prevent fogging and to stop water from getting in, the Easybreath has several valves. When you breathe in, some valves open whereas others close. This is why the sound of your breathing is slightly amplified. This is the same thing that happens when using a regulator when scuba diving.

Relax and breathe naturally through your nose to enjoy the wonders of the seabed.

9. Why do I take in water when I go underwater?

We developed the dry top stop water concept primarily to prevent water from getting into the snorkel when there is choppy water, small waves on the surface or when the user leans their head too far forward. Under the same conditions with a traditional snorkel, the user could swallow the water that gets into the snorkel; this is what we wanted to avoid.

This dry top stop water system only works when the snorkel and float valve are in a vertical position. When free diving, the snorkel is in a horizontal position during the duck dive, this is when water can get into the snorkel.

10. Why can’t you free dive with the Easybreath?

The Easybreath was designed for surface snorkelling, which represents most of the common practice.

It is not possible to free dive for several reasons:

  1. The dry top system does not work in a horizontal position when duck diving.
  2. The volume of air contained in the Easybreath is much greater than that contained in a traditional mask; from 1m deep, the pressure of the mask on the face becomes very uncomfortable.
  3. When you free dive, you need to equalize the pressure afterwards, i.e. hold your nose and blow through it gently as if you are blowing your nose in order to balance the pressure of the ears so as not to pierce your eardrums. With the Easybreath it is impossible to equalize because you can’t get at your nose.

11. Is having a beard a problem?

Yes, we’re sorry to say. What makes the mask watertight is the contact between the smooth silicone skirt and your skin. As with a traditional mask, beards create tiny spaces that allow water to infiltrate.

12. Why is it fogging up?

The exclusive anti-fogging system through respiratory ventilation performs optimally in water above or equal to 18°C. It is essential to wash your Easybreath by hand with dish soap after each week of use. The window of your mask will get dirty due to salt water and the sun and eventually fogs up your mask.

13. What is the valve behind the white cover at the bottom of the mask for?

This valve lets you drain out any water that has got in without you having to remove the mask. If you have a little bit of water in your mask, raise your head and the water will automatically be let out by the valve.

14. Why won’t the strap tighten?

If the strap won’t tighten, this is because the strap has not gone through the small elasticated loop which lies along the strap. Here’s a video with a demonstration on how to adjust your mask.

15. Why is the mask so big?

The first reason is that a large mask that covers the whole face is the only effective way to fulfill the Easybreath promise: Seeing 180° and breathing naturally underwater just like on dry land.

The second reason is that the Easybreath complies with many standards including those concerning snorkels and respiratory effort. The dimensions of the snorkel and the white surround meet these regulations (EN 1972).

16. Why isn’t the snorkel of the Easybreath very long?

Contrary to what many people may think, the snorkel of the Easybreath sticks out of the water more than a traditional snorkel if worn correctly. A traditional snorkel seems longer because it starts from the mouth and not the top of the head like the Easybreath.

If you try breathing through a snorkel and then through a garden hose you will understand that the longer the tube, the harder it is to breathe. To guarantee a level of respiratory effort that meets current standards, we cannot make the snorkel any longer.

17. Why can’t you use the Easybreath for swimming training?

Swimming requires a lot more effort than snorkelling, just as running requires a lot more effort than walking. Swimming laps needs a significant amount of oxygen and your body will automatically switch to intensive mouth breathing. At this point, breathing with the Easybreath would become very uncomfortable.

18. How long does the air supply in the Easybreath last?

The Easybreath does not have an air supply. You do not breathe in the air in the volume of the mask, you breathe in air from the snorkel.
