500 Men's Long Sleeve UV Protection Surfing Top T-Shirt
Filtered by translation missing: Loading reviews…
Man Child - apparently!

Bought the medium (M) size of this for someone who normally wears medium t-shirts (48-40" chest) thinking it would be a proper fit, a bit tight, but that's not bad in a rash vest. It turns out they are not a man, but a mountain at that size as this came in at a child's small (age 12-14). Unless they are not telling me something, I would say this is most definitely not a medium.


This top is excellent to wear. The sizing is smaller than I would like, especially the body length. It is a cozy fit despite being 2 sizes larger than I normally wear but the fabric is very stretchy and comfortable. I love it.

No red lobster

Good armour against UV light and sunburn. Works well. Stretchy enough it doesn't get in the way. Wish list: hope they make one that covers the hand and face too... Ninja UV50 style.

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?

Using it for Work wear

I use this top for work wear as I am outside most days. It is just brilliant, I don't have to wear long sleeve jackets anymore. It does not overheat and handles humidity very well. I cannot believe its taken me so long to use Surf wear for work.

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.

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

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

Hello Sudeep,

Thank you for reviewing for the model 500 Men's Long Sleeve UV Protection Top T-Shirt - Cosmo Blue(8518950) - Your feedback is very important for you in improving the products year by year.

As this Rash vest is designed and developed for Surfing sport and its special features of UV protection and Chlorine but we do not recommend this product considering your usage as this is an occasional usage model, a best fit for a person who swims occasionally.

As i see you are not happy with the usage of the product, i would recommend you to take it to the nearest Decathlon store and get the product exchanged with a another product as every product had warranty of 2 years. our sport leaders would be happy to assist you.

We would stay available for any assistance.



Excellent material

Light and comfortable

Additional Product informations


Main fabric

  • 15% Elasthane
  • 85% 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)

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 fibres filters out UV rays, for long-lasting protection, even after washing. Caution: the elastane contained in the fibre may deteriorate in chlorinated water.

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 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 two-hour sessions.

Support and stability in the 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 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, kitesurfing, windsurfing, wakeboarding, water skiing, sea wading or SUP (stand up paddle boarding).

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.

Surfing sun protection
