Additional Product Information


Main fabric

  • 100% Polyester cationic

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 fibers, 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 protection T-shirt reduces friction with the surfboard or bodyboard. The loose fit of the T-shirt makes it easier to put on and is more comfortable when dry. Choose the fitted cut of the 100 or 500 top if you prefer comfort when wet or wear it under a wetsuit. Limitation of irritation has been proven for sessions of 1 hour. If you plan to surf for more than 1 hour, the 500 UV top will be a more suitable choice thanks to the seamless panels under the arms.

Support system

This UV protection water T-shirt 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. 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 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 the 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 important to protect them effectively.

Behavior 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 behavior: wear sunglasses, wear a hat or cap, regularly apply an appropriate sun block, drink regularly, etc.
