What does UPF 50+ mean?

This product is UPF 50+ certified.

UPF stands for Ultraviolet Protection Factor. It is an index measuring the ability of a fabric or material to filter out ultraviolet rays. The UPF 50+ index is the highest UV protection certification in Europe, according to European standard EN 13758-1. An UV protective garment with UPF 50+ certification blocks over 98% of UV rays, protecting your skin from possible burns and lesions.

By way of comparison, a cotton summer t-shirt often has a protection factor of around UPF 5. This means that 20% of UV rays pass through the fabric, which is a lot for someone who has to stay out of the sun or is exposed to it for long periods of time.

At KER SUN, your safety is our priority. That is why we use our own laboratory to test the UV clothing and accessories we offer on our online shop to make sure they comply with UPF 50+ certification.

About Ker Sun

Ker Sun is above all a personal story. About ten years ago, Claudia, our co-founder, was diagnosed with Lupus, an autoimmune disease that forces her to be extremely careful with her sun protection. That day, she felt like she was losing some of her freedom. Like many, she no longer felt safe going outside.

In 2019, to make wearable sun protection accessible, we launched Ker Sun. Ker Sun's mission is to protect every person from sun damage. We want to give back to those with the most sensitive skin, the freedom to enjoy outdoor activities safely. We also actively participate in the prevention of UV-related diseases.

Today Ker Sun is the first French online store specialized in sun protective clothing and accessories. We distribute different brands and quality products to guarantee you an optimal sun protection.

At Ker Sun, your safety is our priority! All selected sun protective clothing is UPF50+ certified regardless of the color of the fabric. Take clothes that you will enjoy wearing, we take care of your skin.
