Lovely top but very small

This was a lovely top but very small. I ordered age 4 for my 2.5 year old who is really slim and the age 4 was too small. Definitely size ups few sizes!

Fällt mega klein aus

Fällt mindestens 2 Größen kleiner aus ! Geht daher leider zurück.

Schönes Matterial aber zu klein

Die Lieferung kam sehr schnell und das Material fühlt sich gut an. Für unser 11 jähriges Kind war die Öffnung für den Kopf in der Größe für 14 jährige Kinder zu klein, deshalb leider zurück.

Gutes Material aber winzig klein

Dickes stabiles Material, aber mein 9 jähriger Sohn hat nicht in die Größe für 12 Jahre gepasst...

Hi Christian!

Groessen stimmen nicht

Das Produkt ist ansonsten genau das was ich mich vorgestellt habe, aber man sollte besser eine Nummer groesser nehmen.

Fällt größer aus

Meiner 6 jährigen Tochter passt die Größe für 4 jährige

Grösse absurt!

Die Grösse stimmt absolut nicht. Meine Tochter ist 1 Jahr alt und 74 cm gross. Habe ihr die kleinste Größe nicht mal anziehen können.. Mit 4 Jahren ausgewiesen.. Ärgerlich! Sonst sieht das Shirt viel versprechent aus.


kaufe ich zum 2x!

Größenangabe passt nicht: zu klein

Ich habe das Shirt in 128 gekauft. Das soll Kindern zwischen 7 und 8 Jahren passen. Es passt meinem Kind, das sonst Größe 110/116 trägt und 4 Jahre alt ist. Ansonsten tut es was es soll.

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.

Warmth and wind

The minimum water temperature recommended for the use of this UV-protection T-shirt is 22°C if it is worn on its own. Max. session length: 3 hours.This top has neoprene on the front and back to provide warmth even in windy conditions.This top can also be worn under a wetsuit.

How does neoprene work?

By trapping a thin layer of water around the body, the neothermal top works in two ways: 1. the trapped water gradually reheats 2. heat transfer is reduced.The wetsuit and the thin covering of water form a layer of insulation.


The neothermal top is made of fleece textile and neoprene to ensure better thermal insulation.The neoprene is lined with polyester fabric for added resistance to wear.Neoprene thickness: 1.5 mm. Neoprene is a closed-cell polychloroprene elastomeric foam with trapped nitrogen bubbles that have insulating properties.We test and guarantee the thermal quality of our neoprene materials.

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 neothermal top 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. We have added seamless panels under the arms to limit irritation due to paddling movements. Our test protocols confirmed that irritation was indeed limited during three-hour sessions.

Quick drying

The polyester fleece textile is naturally quick drying.An additional water-repellent treatment prevents water absorption to limit shivering in case of wind. It also makes drying easier. The effects of this treatment will decrease after 5 or 6 machine washes; therefore to increase the life of the treatment, use a clear water rinse instead of washing with detergent.

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.

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).

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.

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.
