These water shoes are designed for snorkelling and water hiking. Your feet are protected when you get in the water. Be careful not to damage marine life. 
They have been designed to provide the comfort you need on sandy beaches, which may also have small stones, and pebble beaches.
They’re also suitable for other water sports: canoeing, kayaking, and stand-up paddle board (SUP).

These shoes are designed to be used on stony terrain, coral sands or even pebbles.
It is possible to walk on rocks with these shoes, but you won’t enjoy optimal comfort. Watch out for slippery, algae-covered rocks, however, where the grip may be reduced.

Can I walk on rocks with them?

These aquashoes can be machine-washed with detergent for a cycle at 30°C maximum. Choose a delicate programme.
Air dry and keep away from the sun.

Are these shoes machine washable?

Our Aquashoes have a slim and snug fit to keep your feet hydrodynamic when moving around in the water. We recommend choosing your usual size. If you can’t try them on in person, remember that you can always exchange them.

Diving Mask Type

Water-repellent film laminated directly onto the polycarbonate lens. This film prevents fogging underwater.

Anti-fog film

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

To activate the film, first soak the mask in water and lightly rub the inside of the lens before diving. To optimize the efficiency of the anti-fog system, don’t touch the lens with your fingers that may be greasy (e.g., sun cream). If the lens fogs up, rinse with clean water and rub the inside of the mask lightly with your fingers.

Maintaining the effectiveness of the anti-fog system

The textile strap won’t pull your hair and it has built-in snorkel clip.

2 side straps

Children ages 4 to 6 should try a size XS. 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.

Diving & Snorkeling Masks

Just climb onboard the product and observe while paddling.

Ease of use

Panoramic without any deformation through the large transparent bubble.

Field of vision

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.

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

When snorkeling, 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 this happens, lift 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 carefully sized snorkel makes it easy to breathe safely.

Snorkelling is a simple and fun activity for the whole family! However, keep in mind that this is a physically demanding activity. If you have cardiovascular or respiratory problems (including lung infection, angina, asthma, high blood pressure or heart disease), consult your physician or doctor before using this product. In addition, if you experience fatigue, oxygen deprivation, or dizziness, please remove the mask and exit the water.

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.

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.

It’s especially important for kids to wear proper sun protection. For identical exposure, the effects of the sun are 2 to 3 times stronger on a child than on an adult. It is therefore important to protect them effectively.

Protection for kids

UPF (ultraviolet protection factor) is an international standard that measures 
the proportion of UV rays a fabric lets through to your skin. 
A UPF of 50+ means that the fabric blocks at least 98% of UVB rays and 95% of UVA rays.

What does UPF 50+ mean?

This T-shirt protects against UV rays, but it doesn’t provide complete sun protection. It is essential to consider other factors such as reflections of the sun (off sand, water, etc.), temperature, and time of day. For example, wear a hat and sunglasses, regularly apply sunscreen, and stay hydrated.

How should you behave in the sun?
