One thing to look out for: sand! As with your sunglasses, avoid getting sand on your Easybreath mask to keep the lens from getting scratched up. 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. Then rinse the snorkel to completely remove the sand. To ensure you get the most out of your mask, it's important to rinse it well with clean water after every use. Afterwards, store it in its ventilated pouch.
The Easybreath is now offered in 2 sizes which provide coverage for 90% of the faces of men, women, and kids over 10 around the world:~
- size S/M is designed for adults with thin faces, women, and kids over 10.~
- size M/L is made for an average adult face.
It's best to try on both sizes in one of our Decathlon stores. Once the mask is tightened to your face, if there is no space between your chin and the mask's silicone skirt, you've got the right size. ~
If you can't get to a store, or you prefer to order your Easybreath online, here's how to choose your size from home. ~
With your mouth closed, measure the distance between the dip at the top of your nose and the bottom of your chin:~
- size S/M is designed for adults with thin faces, women, and kids over 10.~
- size M/L is made for an average adult face.
When you receive your mask, put it on to check that there is no gap between the bottom of the mask and your chin.
There are several reasons why water may be getting into your mask: The most common is due to choosing the wrong size. The Easybreath is offered in 2 sizes: S/M for adults with thin faces, women, and kids over 10, size M/L for the average adult face. Gentlemen beware! 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.
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. Use a key that you can fit through the rear vents of the snorkel to unblock the float valve. Then rinse the snorkel to completely remove the sand. The Easybreath mask's snorkel has a float valve, which was designed to keep water entering the snorkel when the water is choppy, when there are ripples on the surface, or when the user leans their head too far forward when looking at the seabed. The snorkel has a float device which when submerged rises in the snorkel to block the entrance. In the event of submersion, remember to blow out when going up to the surface to ensure you let the float go down again.
If the air supply blocks it is because you have tilted your head too far forward or because a wave has passed over your head. The Easybreath® Dry-Top system works to prevent water from getting inside. Your snorkel was likely totally submerged, therefore the float went up to plug the hole. In the event of submersion, remember to blow out when going up to the surface to ensure you let the float go down again. If you had put your head too far forward with a traditional snorkel, you would have found yourself breathing in water. Most of our testers were surprised the first time too!
If you are having difficulty clipping the snorkel onto the mask, it's likely because there is sand 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, don't force it! Rinse the snorkel and the mask. Make sure that there is no more sand left before trying to connect them again.
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 normally through your nose to enjoy the wonders of the seabed.
We developed the Dry-Top 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 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.
The Easybreath was designed for surface snorkelling, which represents 90% of the practice. It is not possible to free dive for several reasons:~
1) The Dry-Top system does not function when horizontal, such as when duck diving ~
2) The amount of air inside this type of mask is much greater than that found in a traditional mask. From just 1m down, the pressure inside the mask becomes very uncomfortable on your face.~
3) When freediving, you must decompress, which means pinching your nose and blowing as if blowing your nose. This is to balance the pressure in your ears so as to not rupture your eardrums. With the Easybreath, it is impossible to decompress as your nose is inaccessible.
Yes. What makes a 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.
The exclusive anti-fogging system through respiratory ventilation performs optimally in water ≥ 18°C. It is important to rinse your Easybreath in clean water after each use. The lens of your mask gets dirty due to salt water and sun, and this eventually makes your mask fog up.
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.
If the strap won't tighten, this is because the strap has not gone through the small elasticated loop which lies along the strap.
The first reason is that a large mask that covers the whole face is the only effective way to fulfil the Easybreath promise: "see 180° and breathe normally 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).
Contrary to what many people may think, the snorkel of the Easybreath sticks out of the water more than a traditional snorkel. 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.
Swimming requires a lot more effort than snorkelling. Just as running requires a lot more effort than walking. Swimming training requires a significant amount of oxygen and your body will automatically switch to intensive mouth breathing. At that point, breathing with the Easybreath would become very uncomfortable.
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.
The Easybreath mask is recommended from 10 years and up.
