Okay product
Great experience
perfect for snorkeling, no leaks, stays in place nicely even for 40 minutes in the sea
Extra mask for underwater adventures :) easy to use, good visibility. I recommend.
Choose your size carefully for a perfect seal. 3 weeks in water at 26°C, no fogging. The visibility of this mask is the most striking point (lateral field, top and bottom) Small downside or rather recommendation: In the event of water intrusion (hair in the seal or movement of the mask following an impact) you may be surprised even frightened because eyes nose mouth will suddenly be in the water. I removed the mask to empty it but I believe the water also evacuates naturally through a valve located at the bottom of the mask. There is no need to panic.
Excellent device
Excellent mask
This mask made me absolutely love snorkeling! You can breathe in it completely naturally through your nose and mouth, it doesn't fog up, and you have a wider field of vision than with classic glasses (the edges distort a little, but that's nothing you can't deal with). At the beginning, I had a problem with the correct adjustment of the straps (so that they are not too loose and the mask does not leak, but at the same time so that they are not too tight and my face does not hurt), but it is only a matter of practice. I am absolutely thrilled and highly recommend!
Mask very good for snockerling, avoids this feeling of compression that we had with the old ones, I was able to stay even longer on surface diving.

EXCELLENT PRODUCT
Very nice to discover the seabed
Excellent product which is a complete change compared to the traditional mask/snorkel! Panoramic screen and smooth breathing... my downside: after about twenty minutes, I have trouble maintaining smooth breathing, and I tire more quickly.
Really great
For me, great options with a soft nose. I recommend .

Additional Product Information
Composition
Skirt: 100.0% Silicone ; Lens (for diving): 90.0% Polycarbonate, 10.0% Styrene Ethylene Butadiene Styrene ; Tube (for diving): 100.0% Polycarbonate ; Frame (for skiing): 100.0% Polypropylene
Before each use, check your easybreath, and especially your child's:
- Hold the snorkel in your hand and move it from left to right. The ball should follow the movement without restriction - Check that the seal is in place, in good condition, and correctly positioned - Check that all of the valves are in placed, lying flat, and that they're not deformed- Check the overall assembly of the mask and make sure that there are no defects in the assembly of the skirt on the frame or in the lens.- Never use the mask without the snorkel
What if my mask is fogging up?
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.
Snorkelling safety
Snorkelling 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.
What is the easybreath adult dive mask - 900?
The Decathlon Easybreath 900 mask shares the same features as the Easybreath 500 (anti-fog, panoramic field of view, easy donning, dry-top snorkelling), but the major difference is this new snorkelling mask offers something new: nose-access. The soft part around the nose allows you to equalise your ears and dive down without the risk of damaging your eardrums. The full power of the Easybreath concept with the ability to go down!
Why does this easybreath mask have a soft nose?
Despite its low volume, when swimming underwater and freediving (to a depth of up to 3 metres), the pressure around you increases. This is what causes discomfort in the ears. The easiest way to compensate for this is to pinch your nose and blow gently to send air into your ears. The pressure can also press the mask against your face. To relieve any discomfort, exhaling through your nose or mouth is the easiest way to reposition the mask.
How does the easybreath work?
The fresh air is projected onto the glass before reaching the nose or mouth via the nasal valves. The constant supply of fresh air reduces the amount of fogging up in the mask.The air packed with moisture and CO² is evacuated through channels located inside the mask's rim, which leads this air into the snorkel. The air is constantly renewed. The flow of air going in and out are separated to avoid mixing in polluted air and allowing you to breathe fresh air.
How does the dry-top system stop water from entering?
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 is fitted with a float that rises to close the opening when the snorkel is submerged. When this happens, remember to take the snorkel out of the water and blow into the mask to make sure the buoy comes back down.
Why is the easybreath mask not made for diving?
The choice of the Decathlon snorkel mask (Easybreath) should be made if the user is mainly looking for high breathing comfort and a wide field of vision. The design of the Decathlon Easybreath mask makes it ideal for people who are mainly observing from the surface and want to do some shallow freediving.
Which easybreath 900 size is right for you?
The Easybreath Adult Dive Mask - 900 comes in 2 sizes and covers 90% of an adult's face.From 10-year-old and for small faces, opt for size S/M and for bigger faces: size M/L.To choose the right size when in the store, tighten the mask so that it fits against your face: there should be no gap between your chin and the bottom of the mask.
