Safety 

Snorkel certified compliant with safety requirements according to European EN 1972 standards. certified by the INPP (French professional Snorkelling institute). 

Accreditation 

When snorkelling, 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 the top.

Snorkelling is an easy and fun family activity! 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.). If in doubt, consult your doctor. 

Snorkelling Safety 

Sand or salt sometimes gets stuck between the valve and the hard part of the snorkel, or at the top of the float, preventing the valve from correctly lying flat and ensuring a watertight seal. If this occurs, simply rinse the snorkel well with clean water and make sure the valve lies flat. 

Valve Maintenance 

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

Wave Guard 

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


Mouthpiece 

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 to drain the snorkel instantly.
High-speed intensive swimming is not recommended, as the valve may get displaced and let water in. 

How to use the valve 

Silicone is a very flexible material that provides superior mouth comfort.

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.

Tempered glass lenses

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.

UV Protection Factor

All our UV-resistant rash guards are UPF 50+, meaning they offer maximum sun protection. 
The sleeve lengths vary, and they’re suitable for different water sports. That said, our line was primarily designed to meet the specific needs of surfers. 
Choose your rash guard based on the duration of your surf session: 1 hour, 2 hours, or 3 hours.

How to choose your rash guard (Part 1)

This Olaian rash guard blocks at least 98% of UVB rays and 95% of UVA rays (UPF 50+), guaranteeing effective protection from the sun. Ideal for water sports, they can be worn in or out of the water. The density of the textile fibres filters out UV rays for long-lasting protection, even after washing. Chlorine-resistant.

UV protection

1 hour: Occasional practice. Choose either a loose fit (easy to put on, comfortable when dry) or a tight fit (comfortable when wet). Look for a loop system so you can fasten the rash guard to your shorts.
2 hours: Regular practice. A rash guard with a drawstring and seamless underarm panels will improve fit and comfort in the water.
3 hours: Intensive practice. A style with added warmth will let you stay out longer.

How to choose a UV protection T-shirt (Part 2: )

At the beginner level, you are just learning to surf or surf only a few times a year. You ride small or broken waves in shallow bodies of water where your feet touch the bottom. We offer a wide range of swimwear for beginners of all body types.

Beginner surfers

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?

Our UV T-shirts meet the needs of the most demanding surfers. They’re also compatible with many other water sports, including kitesurfing, windsurfing, wakeboarding, water skiing, and stand-up paddle boarding.

Suitable for multiple water sports

This top is UV-resistant, but it doesn’t provide total sun protection. Consider other factors like reflections (off water, sand, etc.), temperature, and time of day. Wearing this top is just one part of staying safe in the sun. You should also wear sunglasses and a hat or cap, apply sunscreen regularly, and drink plenty of water.

Ease of use

Panoramic without any deformation through the large transparent bubble.

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.
