Additional Product Information
Composition
Main fabric: 100.0% 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)
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.
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 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 one hour, the 500 UV top will be a more suitable choice thanks to the seamless panels under the arms.
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, kite surfing, 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 kids' 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 kid than on an adult. It is therefore important to protect them effectively.
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.
