Is this product suitable for use at the pool or in the ocean?

Yes. The material of this product has been carefully selected to be resistant to both chlorine and salt water. This means you can enjoy your garment in the pool or at the seaside, without compromising its quality or level of protection.

Does the fabric maintain its UPF 50+ protection when wet?

Absolutely. The UPF 50+ certification of this fabric holds even in wet conditions, ensuring your skin remains protected from UV rays, whether the clothing is dry or after extended time in the water.

Does this product dry quickly after swimming?

Yes. The fabric in this product is designed to help water drain quickly, leading to faster drying for improved comfort and a pleasant feel.

How should I care for it to maintain its quality?

Although it is resistant to chlorine and salt water, in order to prolong the durability of this product, we recommend rinsing it with clean water at the end of a day where it has been in contact with salt or chlorinated water.

If you wish to machine wash this product, we recommend that you follow the care instructions specified on this product sheet or on the label of your garment or accessory.

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.

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

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.

perfetta e leggera

Causa cicatrice alla base del collo ho comprato questao fasciacollo senza essere troppo convinta e ho comprato anche altri prodotti simili, questo lo uso sempre, leggero, traspirante e comodo. Alla fine tra tutti quelli che ho comprato sempre con protezione UV ( di altre marche) uso sempre questo.

Un point faible

Bon point : le tour de cou descend dans le dos et sur le haut de la poitrine. Mais, si on ne l'utilise pas en masque, il a tendance à se laisser aller en accordéon, laissant à découvert la zone sous le menton.

Tour de cou léger, respirant, protection optimale

Après une opération à la base du cou, pour la cicatrisation , je dois protéger cet endroit du corps du soleil. Je suis ravie de mon achat. Sèche très vite, confortable, léger comme une seconde peau, ne serre pas le cou. Je recommande à 100%. Cet article de top qualité vaut bien son prix.

Bonne qualité mais c’est moche

J’aime bien le concept, je voulais un truc qui puisse me protéger tout en étant stylé et portable dans la vie de tous les jours mais c’est moche
