Does the UPF 50+ protection ever wash out?

Our sun protective expertise has allowed us to develop fabrics that filter UV rays mechanically. Thanks to the meticulous choice of textile fibers, their optimized density and our advanced weaving techniques, we guarantee a UPF 50+ protection, without added sunscreens, which persists throughout the life of the product, even after many washes.

Do I need to apply sunscreen underneath my UPF 50+ clothing?

With Ker Sun sun protective clothing and accessories, there’s no need to apply sunscreen on covered areas.

However, for full protection, it’s important to apply sunscreen to any exposed skin. We recommend applying sunscreen 30 minutes before sun exposure and reapplying every two hours or after swimming, in accordance with the instructions for the product you’re using.

Which certification or standard does this product meet for sun protection?

This garment is certified UPF 50+, providing you with the highest level of sun protection. Every fabric, regardless of color, undergoes rigorous testing under the European standard EN 13758-1 for each new production run, ensuring maximum, reliable, and safe protection.

What sets a Ker Sun UPF 50+ clothing apart from regular ready-to-wear clothing?

Ker Sun's UPF 50+ clothing does more than dress you: it effectively shields you from sun-related risks. This protection is built on three pillars:

  1. Exceptional sun protection: Our clothes are made from UPF 50+ certified fabrics. This long-lasting protection creates a permanent barrier against UV rays, going far beyond what standard ready-to-wear clothing can offer.
  2. Optimal coverage for reinforced protection: Each Ker Sun piece is thoughtfully designed to protect the most sun-exposed areas (arms, neck, hands, face, chest, legs etc.) while maintaining elegance and everyday ease of use.
  3. Maximum comfort, even in hot weather: Designed with heat in mind, our breathable, lightweight fabrics and airflow-friendly cuts help keep you cool while staying shielded from UV rays.

Conventional ready-to-wear clothing, which isn’t designed for sun protection, consistently lacks these benefits. At Ker Sun, our mission centers on creating garments that truly defend you from the sun, allowing everyone to enjoy outdoor activities with peace of mind.

avis achats

Bonjour,
J'ai été très heureuse de pouvoir me sentir protégée cet été, avec les manches et mitaines. Seul bémol, le chapeau ne tient pas sur ma tête; j'avais pourtant suivi les mensurations indiquées. A la moindre brise il s'envolait. J'ai dû rajouter un élastique

Bonjour Nathalie,

Merci beaucoup pour votre avis.

Nous sommes ravies que les manches et mitaines vous aient bien protégée cet été ! Nous sommes en revanche désolées que le bob n'ait pas suffisamment tenu sur votre tête malgré le respect du guide des tailles.

Nous vous informons qu'une taille en dessous existe, qui pourrait offrir un meilleur maintien pour une prochaine commande.

Merci encore pour votre retour,

l'équipe Ker Sun

Bob anti-UV-Sylt

Taille grand S/M . Je pensais qu’il était réglable pour la taille, et je vais devoir bricoler l’installation d’un élastique il s’envole au premier petit coup de vent . Dommage car il est léger et les bords protègent bien . Je regrette l’achat de ce bob .

Bonjour,

Merci d’avoir pris le temps de partager votre expérience.

Nous sommes désolés d’apprendre que le bob a tendance à s’envoler facilement.

Nous sommes toutefois ravis de lire que vous appréciez sa légèreté ainsi que la protection offerte par ses larges bords.

Si un article ne vous convient pas lors de l’essayage et qu’il est toujours à l’état neuf, vous pouvez bien entendu le retourner gratuitement.

Si vous recherchez un modèle mieux adapté aux journées venteuses, nous pouvons vous recommander le bob Faro. Celui-ci est équipé d’un cordon de maintien afin de mieux rester en place :

Un bob qui ne tient pas sur la tête

Au moindre léger coup de vent, le bob s'envole. Assez déçue de mon achat. Il aurait fallu un élastique au niveau de la tête ou une lanière pour le maintien sous le cou.

Bonjour,

Nous sommes désolés d’apprendre que le bob ne répond pas à vos attentes et qu’il ne tient pas suffisamment en place lorsqu’il y a du vent.

Nous comprenons que cela puisse être décevant. Chez Ker Sun, nous proposons également différents modèles de chapeaux et casquettes avec cordon ou système de maintien supplémentaire, qui peuvent être mieux adaptés en cas de vent.

Merci d’avoir pris le temps de partager votre expérience avec nous.

Bien cordialement,
Team Ker Sun
