Nice but thin

Usually Rashies are tick and give feeling of protection. This model is thin as thin can be so I'm not sure where it's 50SPF comes from. So far, I'm not having sunburns and love how easy is to take it off.

Item was see through!

I have a pair in black and they are fine but the navy is see through. If you look closely in the photo you on the website you can see it but I didn’t notice this when I purchased them. Black pair is great though

Swim top and very comfortable

Chose the men’s top because the women’s were all black. No white version. Who wants to wear black in the hot sun.

Hello Lynne, thank you for your feedback we will make sure to pass on to our team!

Practical and worthwhile

Excellent cooling feeling when wet, good wicking/brreathability.

Rash guard

Fantastic price and quality

icon-circle-checkmark verified purchase

Good lightweight top for the summer. Worn as sun protective underlayer when playing tennis. It does trap some heat in but better than getting burnt. The main disappointment is how quickly the material discolours after use and washes.

Long needed personal sun protection

I purchased this item for personal protection against the brutal South African sun while swimming in the sea. It fits brilliantly, stays in place, is comfortable and of course protects against those brutal sunrays. I am very happy with this product!

Additional Product Information


Main fabric

  • 15% Spandex
  • 85% 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 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 fibers filters out UV rays, 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 UVA and 98% of UVB 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 chafing, particularly around the neck and armpits. Reduced chafing from paddling movements has been proven for sessions of 1 hour. If you plan to surf for more than 1 hour, the UV top 500 will be a more suitable choice with its seamless panels under the arms.

Support and stability in the waves

This UV protection top 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. For more than 1 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.

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, kite surfing, windsurfing, wakeboarding, waterskiing, sea wading, or SUP (stand-up paddleboarding).

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