Frequently Asked Questions

For which activities is this product designed?

This UPF 50+ sun protective product is specifically designed to accommodate your active days, whether they involve sports or more casual daily moments.

Perfect for hiking, running, tennis, or just taking a walk outdoors, it combines comfort, breathability, and optimal defense against the sun’s rays. Versatile and high-performing, it supports you through every activity, whether you’re on the move or simply seeking comfort during downtime.

Is the fabric breathable and able to wick away perspiration?

Yes, this product is made from a technical fabric that promotes airflow and wicks away moisture. This breathability helps you stay dry and comfortable, even during extended physical activity.

Is this product suitable for my skin type?

Ker Sun’s UV-protective clothing and accessories are designed to provide high-performance protection for all skin types, including the most sensitive.

Certified UPF 50+ and classified as Personal Protective Equipment (PPE) in accordance with current European standards, our products offer the highest level of textile protection against UVA and UVB radiation as defined by regulations.

They help reduce UV exposure during outdoor activities, supporting a safer and more confident experience in the sun.

Does the UPF 50+ protection ever wash out?

The UPF 50+ protection does not 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.

To preserve the quality and durability of your product, we recommend that you follow care instructions carefully specified on this product sheet (see above) or on the label.

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.

Mon haut préféré par temps chaud

Clairement cette chemise est mon haut préféré par temps chaud, voir très chaud.
Elle est ultra légère, respirante, protège parfaitement avec ses innovations jusqu'aux mains, cou.
Et surtout un design très joli qui fait que l'on peut la porter par toutes situations, aussi bien en rando que pour une sortie en ville.

Chemise anti-UV - Sequoia

Seit ich Ker Sun entdeckt habe, hat die sonne ihren Schrecken für mich verloren. Jetzt müssen wirklich nur noch die freien Körperstellen mit Sonnenlotion geschützt werden.
Bei der Passform würde ich mir mehr Reproduzierbarkeit wünschen:
Ich hatte die Bluse letztes Jahr in dunkelblau bestellt und jetzt in hell, beides Mal in L, wobei diese etwas kleiner ausfällt.

Bonjour,
Je souhaite pouvoir porter cette chemise comme surchemise sur un tee shirt. J'hésite entre une taille S et M. Je ne veux pas que cela fasse trop grand. Quelle mesure est la plus importante pour valider la taille ? La chemise est-elle légèrement cintrée ou coupe droite?
Merci

Ker Sun

Bonjour,

Merci beaucoup pour votre message et pour l’intérêt que vous portez à notre chemise !

Pour choisir la taille la plus adaptée, la mesure la plus importante à prendre en compte est le tour de poitrine.

La chemise a une coupe droite, pensée pour la randonnée : elle n’est donc pas proche du corps, afin d’offrir une bonne liberté de mouvement et un confort optimal, même portée en surchemise.

Nous restons bien entendu à votre disposition pour tout complément d’information ou conseil.

Très belle journée à vous,
L’équipe Ker Sun ☀️
