What's up with the sizing?

Just like the swimming trunks. Most of them run slightly too small or too short in the torso area when compared to other brands I have before. My son was 9 (average height and weight) and his tummy was showing all the time when he's moving about in it.

Nice and soft with added sun protection.

Bought this for my child who is fussy and had no complaints. Material was soft and didn’t cause discomfort or marks. Sizing runs a little small compared to other brands.

Good product but small fit- size up for your kids

I purchased this shirt for my boys, who are 3y1m and 5y9m, tall and athletic looking. I purchased hoping to get a couple of seasons out of the shirts, so bought a 4-5 for my 3 year old and size 8 for my 5 year old. The shirts will probably fit for this summer and that's it. Highly suggest sizing up a size for their current size and two sizes if you want more than one summer out of them. They're a slim fit, not sure how they'd go on stocky kids. Nice shirts, but small fit.

The fabric and strings started to frail.

Hi Mr Vignesh Waran,

Thank you for purchacing our product for beach wear, my name is Ali from Olaian Water Department in City Square Mall. I'm sorry to know that the fabric and strings started to frail, please come to Decathlon City Square Mall for a 1 to 1 exchange on the t-shirt.
There is two brands that is for swimming they are Nabaji and Olaian, Nabajii are meant for chlorine water and Olain are meant for salt water, for both product are recommended to be rinse with running tap water after use to prevent chlorine to eat up on the material.
I'm looking forward to met up with you and talk more about the product and other selection.
Yours Sincerely
14 ans for a 9 year old?!

The wearer reports it is a bit tricky to remove when it's wet, however, it is cheap and cheerful, dries quickly and gives a bit of protection during adventurous wet activities.

Product information


Main fabric

  • 15% Elasthane
  • 85% Polyester

How to choose your uv protection t-shirt (part 1)

All of our UV-resistant T-shirts are UPF 50+, i.e. they have the maximum level of sun protection.The choice between them will therefore be made based on the length of the sleeves and will depend on what it will be used for. The constraints are greatest for surfing so we decided to build our range primarily for surfing.For surfing, the choice will be made according to the duration of your sessions: 1 hour, 2 hours or 3 hours.

How to choose your uv protection t-shirt (part 2: according to the duration of the session)

1 hour: Occasional practice. You can choose between a loose fit (priority to ease of dressing and comfort when dry) or a fitted cut (priority to comfort when wet). A loop system to connect it to the shorts ensures the stability of the product.2 hours: Regular practice. Comfort when wet is enhanced by the seamless panels under the arms and the drawstring which further increases stability.3 hours: Intensive practice. Additional warmth to help you stay in the water for longer.

Uv protection even when wet.

The fabric of this OLAIAN UV-resistant product blocks at least 98% of UVB radiation and 95% of UVA (UPF 50+).This guarantees effective protection from the sun. It can be used both in and out of the water, for water or nautical sports. UV radiation is filtered by the density of the textile fibres, for long-lasting protection, even after washing.

What does upf 50+ mean?

UPF is a sun protection factor (Ultra Violet Protection Factor) and is standardised worldwide.It defines the protection level of a fabric and more precisely the proportion of UV rays it lets through.To meet the standards, it must block at least 95% of UV rays. UPF 50+ means that the fabric blocks at least 95% of UVB and 98% of UVA rays.

Reduced chafing

This UV-resistant T-shirt helps limit rubbing and chafing due to contact with the surfboard or bodyboard. It can also be used under a wetsuit to limit chafing, particularly around the neck and armpits. Limitation of irritation related to paddling movements has been proven for sessions of one hour. If you plan to surf for more than one hour, the UV 500 top will be a more suitable choice thanks to the seamless panels under the arms.

Support system

This UV protection top has a loop at the front to attach the cord of your swim shorts to stop the top from riding up while you surf. This solution is recommended for sessions up to one hour. After an hour we recommend that you choose the UV 500 top, which also has a drawstring at the hips to ensure better stability. Unwanted riding up of the top could cause irritation to the lower abdomen.

Warmth and wind

The minimum water temperature recommended for the use of this UV-protection T-shirt is 22°C. Air temperature may increase or decrease this recommendation.Our thermal models (over 2 hours) are made of either fleece, neoprene or both. The presence of wind can have an impact which can be uncomfortable as soon as the wind exceeds 15 km/h: In this case, choose a model with neoprene.

Multi water sports uv protection t-shirt

Our UV tops are designed to meet the needs of the most demanding surfers.Our design choices also make them compatible with other water sports such as swimming, kitesurfing, windsurfing, wakeboarding, water skiing, sea wading or SUP (stand up paddle boarding).

Protect the little ones!

Young skin is very sensitive to the sun as children's defence systems are established after the age of 3. With 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.

Behaviour when in the sun

Although this t-shirt protects against the sun, phenomena such as reflections (from water, sand ...), heat, time of day, etc. must be taken into account.Wearing this T-shirt does not exempt the wearer from adopting suitable behaviour: wear sunglasses, wear a hat or cap, regularly apply an appropriate sun cream, drink regularly, etc.

Sun-protection guide

What is the olaian brand?

TRIBORD surfing products are becoming OLAIAN, the new Decathlon brand dedicated to surfing, bodyboarding & skimboarding. Gradually, the branding of all our surfing products will be replaced. This is why your product may have a different logo to the one in the picture illustrating the product.

Score to compare the environmental impact of products

The environmental impact of the product is calculated over its entire life cycle and with different indicators. An overall score (ABCDE) is attributed to help you easily identify the products with the best environmental performance by comparing products of the same type with one another (T-shirts, trousers, backpacks, etc.).Decathlon chose to apply this voluntary environmental labelling scheme.For more information, visit:
