Hello Tina,

Thanks for the 5-star review. We are happy that the rash guard is the right product for you. Have a good day. :)

Good product

Can't really say how much it protects for the sun as I have not made any "tests", I was already tanned by the time I got it :P. But it is a good shirt, it stretches good to fit. I think it is perfect for the price and feels good quality. *I'm not an expert on this products but at least for me it met my expectations.

Super Bekleidung fürs Wasser

Habe das Shirt beim Schwimmen getragen. Ist sehr angenehm in kühlen Sommergewässern-es schwimmt sich länger ohne auszukühlen. ABER: Hinweis für die Nutzung beim Schwimmen: Hals- und Achselbereiche mit Vaseline gegen das Scheuern schützen (ihr werdet schon merken wo)

UV-Shirt eng anliegend

An sich sehr gutes, robustes UV-Shirt, mit dem man sich sehr viel Sonnencreme spart. Sitzt gut, eng anliegend, dadurch auch im trockenen Zustand nicht zu warm. Sobald es nass ist, ist es schön kühl. Im Vergleich zu dem billigeren eng anliegenden UV-Shirt ist der Schnitt besser, da in der Achsel keine Naht verläuft. Es wäre schön, wenn es dieses Shirt auch in helleren Farben gäbe, so wie die billigeren UV-Shirts, z.b. komplett blau. Im Vergleich zu einer älteren Version wurde leider der Kragen gekürzt, sodass dieser den Hals jetzt kaum noch schützt. Auch ist der Kordelzug im Vergleich zur älteren Version leider deutlich gekürzt worden. Die neu hinzugefügte Schnalle ist Geschmackssache, an sich praktisch, jedoch stört sie beim Kajakfahren. Die Größen sind leider auch nicht konstant. Wenn man das selbe Shirt schonmal vor längerem gekauft hat, kann man somit nicht einfach die selbe Größe nochmal bestellen. Der Größenberater hat in diesem Fall zwar ausnahmsweise die richtige Größe angegeben, jedoch kann man diesen ohne Kenntnis der tatsächlichen Produktmaße nicht gut einschätzen. Hier könnte sich Decathlon einiges an Retourenaufwand sparen, wenn die aktuellen exakten Produktmaße immer auf der Website mit angegeben wären.

Additional Product Information


Main fabric: 82.0% Polyester, 18.0% Elastane

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 anti-UV 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. The density of the textile fibres filters out UV rays, for long-lasting protection, even after washing. Caution: the elastane contained in the fibre may deteriorate in chlorinated water.

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 UVA and 98% of UVB 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 diving suit to limit rubbing, 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 chafing was significantly reduced during 2-hour sessions.

Support and stability in the waves

This OLAIAN UV-resistant top has a drawstring at the hips. This lets you tighten the top so that it stays firmly in place. It has also been designed so that the drawstring of your boardshorts can be attached to it to stop the top from riding up while you surf.

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 2h) 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 watersports 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 watersports such as swimming, kite surfing, windsurfing, wakeboarding, water skiing, sea wading or SUP (stand up paddle boarding).

Behaviour when in the sun

Although this T-shirt provides protection from the sun, phenomena such as reflections (from the water, sand, etc.), 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.

Product testing

Developed and tested by our design teams in Hendaye, France. The components used for this product are laboratory-tested to ensure the best possible quality and durability.
