UV protection

UPF (ultraviolet protection factor) is an international standard that measures  the proportion of UV rays a fabric lets through to your skin.A UPF of 50+ means that the fabric blocks at least 98% of UVB rays and 95% of UVA rays.

What does UPF 50+ mean?

Our UV T-shirts meet the needs of the most demanding surfers. They’re compatible with many other water sports, including swimming, kitesurfing, windsurfing, wakeboarding, water skiing, and stand-up paddle boarding.

Suitable for multiple water sports

This top is UV-resistant, but it doesn’t provide total sun protection. Consider other factors like reflections (off water, sand, etc.), temperature, and time of day. Wearing this T-shirt is just one part of staying safe in the sun. You should also wear sunglasses and a hat or cap, apply sunscreen regularly, and drink plenty of water.

Boardshorts are swimming shorts. They were created in the 1950s for surfing.
Over the years, they have become a popular style of swimsuit.
The name comes from their use in aquatic board sports, like surfing.
They were developed primarily to limit chafing against the board.

What are boardshorts?

For sessions under 1 hour
It’s important to choose boardshorts that you don’t constantly have to adjust while you’re out on the water. Shorter styles are recommended for bodyboarding to ensure greater range of motion. Quick-drying material is also key to prevent sand from sticking.

Boardshorts design

  
Our 100 long boardshorts are available in S, M, L, XL, and XXL.
   
We recommend choosing a shorter pair if you’re widest in the torso and legs, 
while a longer style is more suitable if you have a slender build.

Sizes

It isn’t easy to adjust your boardshorts while you’re surfing, so it’s essential to choose the right waistband. Look for an elastic or semi-elastic waistband with a drawstring or a flat design for better hold.

Wave resistance

    Our boardshorts are designed specifically to limit chafing, a common issue for surfers.

In aquatic board sports like surfing, it’s particularly important to have maximum range of motion,
so your boardshorts should have an ample amount of stretch.

Waterlogged boardshorts can easily become caked with sand. These boardshorts are quickdrying and won’t get bogged down.

Quick-drying

Boardshorts length comes down to personal preference. Shorter styles, for example, provide greater freedom of movement. The average size L is 20 inches long (51 cm).

Length

These boardshorts have three pockets, including two on the sides. The pockets are mesh-lined to drain water and sand more quickly.

Pockets

Our 100 long boardshorts feature an anatomic semi-elastic waistband that keeps them securely in place even when you fall or have to dive into the waves.

Waistband

These boardshorts feature built-in stretch-mesh briefs for an even better fit and reduced chafing.

Inner briefs

In summer, when the weather’s hot but the water’s cool, surfers tend to stay out on the water longer without changing their equipment. This increases the risk of sunburn.
Did you know? The water’s surface reflects 10%–15% of UV rays, leaving 40%–95% to penetrate to a depth of up to 25 cm. This is why pairing boardshorts with sun protection (e.g., UV top) is becoming essential for surfing in warm weather.

The textile mesh prevents grains of sand from getting stuck.

Our team of designers has developed a UV-protection T-shirt that is perfectly suited to surfing in warm water, for sessions lasting up to an hour

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 1)

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.

How to choose your UV protection T-shirt?(Part 2: According to the duration of the session)

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 fibres filters out UV rays, for long-lasting protection, even after washing.Chlorine-resistant.

UV protection even when wet

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.

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.

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 one hour. For more than one 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.

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.

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).

Multi water sports UV protection T-shirt

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 sunscreen, drink regularly, etc.
