Far too small for the size.

Wouldn't bother buying this unless you want to buy a much bigger size. Had to buy a size 12 to fit a 5 year old.

Good Swim shirt

Choose a size bigger than you would usually get. It is a small/slim fit. Does the job and is very soft and lightweight.

Amazing price

Bought one of these tops for each of my kids. My 10 y/o usually wears size 11/12 and the 14 fit him well. My 8 y/o usually wears 9/10 and the size 12 fit him perfectly. They have worn them swimming already and really keep their shape.

Additional Product Information


Main fabric: 84.0% Polyester cationic, 16.0% Spandex

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

All of our UV-resistant T-shirts are UPF 50+, i.e. they offer 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. The density of the textile fibers filters out UV rays, for long-lasting protection, even after washing.

What does upf 50+ mean?

UPF is a sun protection factor (Ultra Violet Protection Factor) and is standardized 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. Reduced chafing from paddling movements has been proven for sessions of up to 1 hour. If you plan to surf for more than 1 hour, the UV 500 top will be a more suitable choice with its 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 1 hour. For more than 1 hour, we recommend that you choose the UV Top 500, which also has a drawstring at the hips for 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 72°F. 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 that can be uncomfortable as soon as the wind exceeds 9 mph: 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 paddleboarding).

Protect your little ones!

Young skin is very sensitive to the sun as children's defense 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 very important to protect them effectively.

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.
