However, if you are planning a more intense sporting activity outside of the water, we offer other models specifically designed to meet your needs in terms of sports performance and comfort.

How should I care for it to maintain its quality?

The UPF 50+ protection does not wash out.

Our sun protective expertise has allowed us to develop fabrics that filter UV rays mechanically.

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.

Couleur

Les bandes de couleur bleue semblent degorger sur les bandes de couleur blanche. Le resultat n est pas net.

Bonjour Madame,
Merci d’avoir pris le temps de partager votre retour.

Nous sommes sincèrement désolés que le rendu de votre t-shirt de bain anti-UV Moorea ne soit pas à la hauteur de vos attentes. Il ne devrait en effet pas y avoir de transfert de couleur entre les bandes.

Afin que nous puissions analyser ce problème plus en détail et envisager un renvoi si nécessaire, pourriez-vous nous envoyer une photo à l’adresse bonjour@ker-sun.com ?

Nos produits sont certifiés UPF50+ selon la norme européenne EN 13758-1, et nous attachons une grande importance à leur qualité et à leur durabilité. Votre retour va nous permettre d’améliorer encore nos standards.

Merci encore pour votre vigilance et votre confiance.

La protezione che cercavo

Ho la tipica carnagione chiara e molti nei scuri, la schiena è quella più difficile per me dove applicare la protezione solare e sono anche una tipa calorosa e avevo remore se avrei sofferto il caldo. Ma sono contentissima dell'acquisto, appena si bagna mantiene freschi anche col caldo assolato e spalle e schiena finalmente non mi preoccupano più di essere costantemente incremati da seconde persone. Qualità del materiale ottima e color albicocca splendente come in foto.

Buongiorno,

Grazie per la sua recensione così positiva!

Siamo lieti che il nostro capo anti-UV abbia risposto perfettamente alle sue esigenze, sia in termini di protezione che di comfort termico. I nostri tessuti sono stati selezionati proprio per offrire una sensazione di freschezza anche con temperature elevate, ideali per chi, come lei, ha la pelle chiara e sensibile.

Le auguro una buona estate, ben protetta dal sole.
Cordiali saluti,
Il Team Ker Sun

Funktionales Shirt

Passform ist gut, die Ware ist einfach bisschen fest und plastikartig. Das geht aber wahrscheinlich nicht anders, wenn man den UV-Schutz haben möchte

Guten Tag,

vielen Dank für Ihr ehrliches Feedback.
Wir freuen uns, dass Ihnen die Passform gefällt. Das Material ist bewusst so gewählt, um den optimalen UV-Schutz zu gewährleisten, auch wenn es dadurch etwas fester und weniger weich wirkt.
Wir hoffen, dass Sie das Shirt dennoch gut tragen können.

Mit freundlichen Grüßen
Ihr Ker Sun Team
