Snorkeling is an easy and fun activity for all the family! Breathing through a snorkel is more physically demanding than regular swimming. If you feel tired, short of breath or dizzy, remove your mask and snorkel and get out of the water.
The use of this product is not recommended if you have cardiovascular problems (chest infection, angina, asthma, high blood pressure, heart disease, etc.). Consult your doctor if in doubt.

Snorkeling safety

Children ages 6 to 10 should try a size S. After age 10, size M is recommended for narrow faces, and size L for wider faces.

Sizing

Place the mask on your face without the strap. Press to make sure the mask is firmly in place.
If the mask “suctions” properly and stays on your face, that means it fits and will be watertight.

If it falls off, you’ll need to try another size, as water will be able to seep in.

How to choose the right mask size

New mask: Wash your mask with liquid soap and warm water. Use your fingers to remove any grease. Don’t use a sponge. 

Before each use, spit into your mask and wipe the lens with your fingers to rinse it.
Wet your face to limit heat loss between the skin and your mask lens. This will help minimize fogging.

Use an anti-fog spray to eliminate fog completely.

Prevent your mask from fogging up

Silicone is a very flexible material. It gently moulds to the contours of your face, creating a watertight seal.

Silicone

Tempered glass is two to five times more durable than traditional glass. It’s more scratch resistant than a plastic lens. If it shatters, it breaks into small pieces, reducing the risk of major injury. Do not jump or dive into water when wearing or holding the mask.Don’t leave your mask in direct sunlight or in a hot car just before using it.For children’s safety, size S is made with plastic.

Packaging

When freeSnorkeling, immersion or splashing can cause water to enter the tube. If this happens, the bottom valve makes it easier to expel the water. Unlike traditional snorkels, most of the water is drained from its lower valve, so the diver doesn’t need to blow hard to push the water out of the top.

Valve

Blow gently to expel any accumulated water. Inhale carefully after draining, as some water may remain in the snorkel. If in doubt, don’t panic. Raise your head out of the water and the snorkel will drain instantly. High-speed intensive swimming is not recommended, as the valve may get displaced and let water in.

How to use the valve

Sometimes sand or salt gets stuck between the valve and the rigid part of the snorkel, preventing the valve from creating a watertight seal. If this occurs, simply rinse the snorkel well with clean water and make sure the valve lies flat.

Valve maintenance

The mouthpiece is the part of the snorkel that fits in your mouth. Ours is one of the most comfortable on the market.

Mouthpiece

The snorkel’s size and volume are suitable for an adult’s breathing.

Snorkel tube

The wave guard is located at the top of the snorkel. Its curved shape limits water entry in choppy seas.

We recommend size M for narrower faces and size L for larger faces.

Tightening Type

Hydrophilic film laminated directly onto the glass. This film prevents the lens from fogging up during use.

Anti-fog film

This mask needs no preparation (toothpaste, flame, anti-fog spray) before use. 

To optimise the effectiveness of the anti-fog system, do not touch the lenses with your fingers or with anything greasy. Such as sunscreen, for example.

If the lens fogs up, rinse with clean water and rub the inside of the lens lightly with your fingers. 

You can also clean your mask with soap and water, then rinse it.

Maintaining the effectiveness of the anti-fog system

Ultra-strong, tempered glass is two to five times stronger than traditional glass. If it breaks, it shatters into small pieces, greatly reducing the chances of injury to the face.
It also has better scratch resistance compared to a polycarbonate lens.

By placing your mask on your face without the strap, and pressing down on it with your hands while holding your breath, you can check that it fits you properly.
If the mask “suctions” well and sticks to your face—perfect! It’s your size and will be watertight in the water. If, on the other hand, it slips and falls off, it’s because air is getting through and water will seep in, so you need to try another size or change the model and shape.

- Hold the snorkel in your hand and move it from left to right. The ball should follow the movement without resistance.
- Check that the seal is present, in good condition and correctly installed.
- Check that all the valves are present, not deformed and are lying flat.
- Check the assembly of the mask and make sure that the skirt is correctly fitted on the frame and glass.
- Never use the mask without the snorkel.

Before each use, check your Easybreath, and especially your child's

If it fogs up over your eyes, we recommend repeating the 4 steps set out above, properly repositioning your Easybreath mask, and checking that the size of your Easybreath is correctly fitted to your face. If the issue continues, do not use the mask and contact your closest Decathlon store.

What if my mask is fogging up?

Snorkeling is an easy and fun activity for all the family! Breathing through a snorkel is more physically demanding than regular swimming. If you feel tired, short of breath or dizzy, remove your mask and get out of the water.
Do not use this product if you have cardiovascular or respiratory problems (lung infection, angina, asthma, hypertension, heart disease, etc.). If in doubt, consult your doctor.

The Easybreath 500 is an easy-to-use, full-face snorkeling mask designed by Decathlon. Same great features as the previous model: 180° vision, anti-fog, easy to put on. We’ve made this mask more robust, with a more comfortable skirt. It’s also 20% easier to breathe in. New innovative features: “Dry-top-release.” Now you can keep breathing when a wave washes over you.

What is Easybreath?

Easybreath: a mask that allows nose and mouth breathing, offering a wide field of vision and an anti-fog system through air circulation. Available for adults and children.

Easybreath + (540): in addition, an acoustic valve that allows you to speak more audibly at the surface, with your head above water (without having to remove your mask!)

Easybreath 900: a soft nose that lets you equalise the ears and allows you to descend to depths of up to 3 m. Don't stay on the surface, get down there!

Which Easybreath masks are available at Decathlon?

Fresh air is pushed towards the lens before it reaches the wearer’s nose and mouth, which helps keep the mask from fogging up.

The moisture- and CO₂-rich air is then pushed out through channels located inside the mask’s rim. The air is constantly renewed. By separating the flow of air going in and out of the mask, the wearer is always breathing in fresh air. Licensed under Ocean Reef Group.

How does the Easybreath work?

The mask uses Dry-top technology. This system was developed to stop water from getting into the snorkel when there is choppy water, small waves on the surface, in case of submersion or when the user leans their head too far forward to observe the seabed. The snorkel has a float that rises to close the opening when it is immersed under the surface of the water. When this happens, remember to blow when the snorkel is taken out of the water to make sure that the float descends properly.

How the dry-top system stops water from entering

The air volume of the Decathlon snorkelling mask is much greater than what is held in a traditional mask.
One metre below the surface, the pressure of the mask becomes very uncomfortable. When freediving, pressure needs to be reduced, but this is not possible with the Easybreath because your nose is not accessible.

Can I dive with my Easybreath 500?

This full-face snorkeling mask is comfortable to wear and provides a wide field of vision. 
It’s ideal for people who want to observe the world underwater from the surface.

Why choose Easybreath over a traditional valve mask?

The Easybreath 500 mask comes in 2 sizes that fit 90% of adult faces. For smaller faces, choose S/M. For larger faces, choose size M/L.

To choose the right size in store, tighten the mask to ensure it fits against your face. There should be no gap between your chin and the bottom of the mask.

Choosing your Easybreath 500 mask size

Having a beard will prevent your mask’s skirt from fitting properly. If you have a beard, this mask may not be watertight. If you want to be sure no water will enter your mask, consider shaving. Alternatively, you might also try using a thick balm such as Vaseline.

Can I wear the Easybreath 500 if I have a beard?

You can repair your Easybreath mask to extend its lifespan. After-sales service is available at your local Decathlon store. Replacement parts (strap, cover, snorkel, valves) are all available online or in store. 
strap - 8316952, valve - 8363399, snorkel - 8506099, white cover - 8520085.

Can my Easybreath 500 mask be repaired if it breaks?

Most glasses will distort the mask skirt and prevent a watertight seal. As a result, using this mask with glasses is not ideal.

Can I wear glasses with my Easybreath mask?

Watch out for sand! Keep your Easybreath mask away from sand to avoid scratching the lens. In the presence of sand, do not force the snorkel into place. Rinse the snorkel and mask first. Sand can also clog the float valve inside the snorkel. Use a key that you can fit through the snorkel’s rear vents to unblock the float valve, then rinse the snorkel thoroughly.

The two-chamber design of the product prevents condensation from forming.

Use the side clips to attach the OLU buoys to one another for even more fun!

Flexibility

Our design teams developed this observation buoy for children and adults who want to explore the coastal seabed without putting their heads under water.

The Olu 120 is a new way of snorkelling. This DECATHLON invention makes snorkelling much easier. 
The Olu 120 is an inflatable product that allows you to observe the seabed without putting your head under water, while remaining supported by an inflatable structure. Snorkelling becomes more pleasant: with your head out of the water, you can move, talk, and chat, while still observing!

What is the OLU 120 observation buoy?

The OLU 120 is available in 3 sizes: Why? The users stay on the top to observe, so several sizes are necessary to be in the best position to observe, depending on each person’s size. Therefore, the size depends on the user’s weight. 
Size S: For a weight less than 40 kg (88 lb)
Size M: For a weight between 40 kg (88 lb) and 65 kg (143 lb) 
Size L: For a weight over 65 kg (143 lb)

How to choose the size of your OLU 120

The clips on the sides can be used to attach several OLU 120 buoys side by side. Stay together, keep an eye on the kids, or simply enjoy the experience together, thanks to this small, easy-to-use accessory!

What is the point of the clips on the sides of the OLU 120?

The OLU 120 is inflated in two steps for two reasons:
- first, to limit the formation of condensation. This is where the OLU 120 is innovative, because it has an air circuit that prevents condensation from forming when being inflated.
- second, for your safety. If one of the chambers is accidently punctured, the second one is still there to support you.
The large black valve at the rear is used for quick and easy deflation.

Why is the OLU 120 inflated in two steps?

The Olu 120 is covered with a transparent film that offers a clear view, without deformation. To make the most of it for longer, take good care of it! Avoid anything that could scratch or cloud the film, like sand, stones, sunscreen, or other abrasive or greasy products.

How to make the most of the OLU 120?

Depending on its position, the sun may cause some slight reflections in the viewing chamber. No need to panic. Just use your hands to create some shade, and you can carry on observing.

What can I do if there are reflections on the OLU 120?

The air circuit prevents condensation from forming in the Olu 120, but small patches of condensation may appear on the top of the bubble, especially when getting out of the water. Don’t worry. Once back in the water, the condensation disappears. All the walls reach the temperature of the water and the condensation evaporates.

What can I do if there are patches of condensation on the OLU 120?

Size S: weight < 40 kg (88 lb) - 430 grams.
Size M: 40 kg (88 lb) < weight < 65 kg (143 lb) - 520 grams.
Size L: 65 kg (143 lb) < weight - 610 grams.

The weight of the OLU 120

At Subea, the Decathlon diving brand, we decided on a simple way to define the difference between our freediving and snorkelling products: From the moment you hold your breath and swim under the surface of the water even a few metres, it is freediving. On the other hand, if you stay on the surface, this is snorkelling.

What is the difference between freediving and snorkelling?
