I am the mother of a 9-year-old girl, Anna, who has lupus. When she was diagnosed four years ago, I was first in shock, then overwhelmed with panic. The sun and UV rays suddenly became our biggest enemies. […]

The UV rays around us are extremely harmful, even if we’re not always aware of it. I’m proof of that. I’ve undergone five facial surgeries, despite never intentionally exposing myself to the sun. […]

Emmanuel M.

UV Zip-up T-shirt - Boston

Very effective.

Very effective.

I hiked under the sun for 10 days, and this tee is incredible. It gives a real sense of safety and protection—especially important for someone like me who can no longer expose themselves to the sun. It’s nothing like a regular t-shirt. Even though the temperature was over 30°C and I was definitely hot, I never once felt attacked by the sun. That made me have more energy to walk. I hadn’t realized before that when I used to hike, I was constantly battling the sun’s harsh rays—or I’d have had to reapply SPF 50 every hour. I returned from vacation without getting burned and without slathering on gallons of sunscreen. I’m very happy!

UV Pant - Saint-Malo

Super light and guaranteed protection

I love this product. It has a great fit, lightweight fabric, and is comfortable to wear while providing excellent protection.

Sylvia P.

UV Swimsuit - Pacific

Very pretty swimsuit

It’s incredibly comfortable and easy to put on and take off thanks to its large zipper. The color is very flattering, and I’m happy to be able to swim safely. The back is lined, and the recommended size (S) is perfect for me. Thank you, Ker Sun!

UV Bucket hat - Léonard

The best

The best hat I’ve ever found for my son. I feel delighted and reassured when he wears it. Thank you, Ker Sun, for your outstanding products.

Ker Sun, the expert in high-performance UPF 50+ Clothing and Sun Hats

At Ker Sun, we are revolutionizing sun protection thanks to our UV-protective fabric expertise. As the French reference for UPF 50+ clothing and sun hats, our mission is simple: to offer safety and peace of mind to those who are most delicate or intolerant to the sun, with a threefold requirement: high-performance sun-protective hats and clothing, made from ultra-technical fabrics certified UPF 50+, an innovative design to maximize coverage, and unparalleled comfort in hot weather. Ker Sun is thus recommended by French and European dermatologists.

Science at the heart of our UPF 50+ certified clothing design

Every Ker Sun fabric undergoes rigorous lab testing to ensure UPF 50+ sun protection, offering excellent defense against harmful UV rays. Unlike typical summer clothing and sun hats, which often allow a significant amount of solar radiation to pass through, our UPF 50+ certified textiles act as a built-in sun barrier, shielding you from associated risks.

UPF 50+ represents the highest level of sun protection recognized by international official standards, and it is precisely this level of safety that our garments offer. We comply with the most demanding UPF (Ultraviolet Protection Factor) testing standards, evaluating, among other things, our materials according to European standards EN 13758-1 or EN 13758-2. In order to guarantee total safety, our testing process is uncompromising: each production batch undergoes several UV protection performance validation cycles before being approved for sale.

Maximum coverage, absolute comfort: our standards for our UPF 50+ clothing and sun hats

Beyond UV protection, at Ker Sun, we design our UPF 50+ clothing and sun hats with the highest standards of coverage, thermal performance and design. Our lightweight, breathable and quick-drying fabrics are developed to offer optimal thermoregulation, even in intense sunlight.

  • Optimal coverage: We pay particular attention to developing practical tips on clothing to maximize the surface area of the skin covered. For example, a magnetic collar that can be raised, found in particular on our sun shirts, to optimize protection of the back of the neck and neck.
  • Modular protection: We are developing a range of sun protective accessories to protect areas of the skin not covered by clothing, providing enhanced sun protection that can be adapted to individual needs.
  • Advanced textile technology: The fabrics we use for our UPF 50+ clothing have an innovative weave and a low weight that guarantees intrinsic sun protection, while preserving their extreme lightness.
  • Neat design: Style and quality are also at the heart of the design of our sun protective clothing and sun hats, to promote their everyday use.

Sun protective clothing recommended by dermatologists

At Ker Sun, we work in partnership with dermatologists, associations and healthcare professionals to continuously optimize our UPF 50+ technology. Our UV-protective clothing is designed for the most delicate skin, including those prone to sun intolerance, sun allergies or increased risk of skin cancer.

What's more, unlike sunscreens that require repeated applications, Ker Sun's UPF 50+ clothing provides continuous and even protection against UV rays, effortlessly and without compromise. Whether for sports, travel, water activities or everyday use, we have designed our clothing to make sun protection as simple as it is effective.

Sun protection, a daily habit thanks to UPF 50+ sun hats and UV-protective clothing

At Ker Sun, we have a conviction: for effective protection, sun protection should not be occasional, but integrated into everyday life. Each exposure to the sun leaves an imprint on the skin, which is why we have designed a complete range of UPF 50+ clothing and sun hats for women, men and kids, adapted to the needs of each.

Therefore, we have developed a large collection of UPF 50+ clothing for women, meeting their needs, desires and requirements. We offer clothing, accessories and women’s sun hats, designed to accompany them in all their activities, whether everyday, aquatic or sporting. All our cuts and colors are designed to allow them to protect themselves from the sun with the elegance, style and comfort they desire. Whether it's for women’s sun protective tees, women’s sun protective swimwear (rashguard) or sun protective accessories, our collections are designed so that everyone can protect themselves according to their tastes.

Similarly, we have designed a collection of UPF 50+ clothing for men, combining unparalleled comfort in hot weather with a modern design. Our products, whether men’s sun protective tees, men's sun hats, men’s sun protective swimwear (rashguard) or accessories, are designed to meet men's requirements for comfort and practicality. They offer optimal protection against UV rays while guaranteeing freedom of movement and superior comfort. Our models, suitable for everyday life as well as for outdoor activities, allow every man to benefit from high-performance and technical sun protection, without compromising on comfort and style.

And because young children's skin is even more vulnerable, our UPF 50+ clothing for kids’ and babies’ provides optimal protection from the earliest months, with ultra-soft, breathable fabrics that are perfectly suited to their delicate and fragile skin. We have designed every cut, every material and every finish to ensure total comfort while guaranteeing an effective barrier against the harmful effects of the sun.

Wearing Ker Sun means choosing innovative textiles that promote health, with UPF 50+ clothing and accessories designed for effective sun protection, optimal coverage and absolute comfort, whatever the activity. Sun protection should never be an option, it should be a given. Our skin is delicate, let's take care of it!
