It was ready comfortable and beautiful design to wear. There's a minor improvement that I would like to suggest of my own opinion by adding an elastic loop at the wrist area on both sides so that where we are swimming the wrist area cloth will not be a pullback that causes annoyances during lapping.

To short

I really like the top but it is too short and leaves my back and belly exposed to the sun. This defeats the purpose of wearing it. Might work for quite short people but not for me. I noticed in the reviews that I am not the only one with this issue. Maybe the design can be changed or a "tall" version could be offered in future?

Surfing Top T-Shirt - 500 Men's Long Sleeve (Blue)

I bought this not for surfing but for sailing. It's perfect for the warmer months in Hong Kong. You can just wear this T-Shirt and your upper body, neck and arms are protected from the strong sunlight. Another good point is that it does not get soggy when it gets wet. Since I bought it, the weather has not been warm enough for me to sweat much during sailing. I look forward to trying out its sweat dissipation ability soon. Happy with this purchase and will highly recommend it.

Very comfy

The best I ever had

Stitching quality

Stitching quality of this product is not very good some part of the T-shirt's stitching has been damaged after a few use. I am happy that I’m not getting tanned

Design is very bad

This top is extremely slim fit, even thin people look very fat!!

Slightly too small although I picked XL

XL size was more like European M, so I found it too small compared to what XL should be

Product quality and longevity

By look this product was good, i swim almost everyday and over the time realised the product material was too light and it started stretching. I have stopped using it as the fit is gone and when in water it keeps moving around the body. Picked up another brand which is better and using it since 6+ months

Olaian 500 Long Sleeve UV protection surfing top

Colour is good enough... there should be more colours available that are striking in shade so surfer is more visible while in the water... Fit is good Size is good but vertical length should be longer by at least 2 in so as not to expose the surfers’ abdomen while in action

Additional Product Information


Main fabric

  • 85% Polyester cationic
  • 15% Spandex

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. Caution: the spandex contained in the fiber may deteriorate in chlorinated water.

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 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 irritation was indeed limited during 2-hour sessions.

A system for support and stability in 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 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).

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.
