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.

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:

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.
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.
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.

Très efficace

J'ai randonné sous le soleil pendant 10 jours. Ce tee shirt est formidable.
. Une vrai sensation de sécurité et de protection. Moi qui n'est plus le droit de m'exposé au soleil. Rien à voir avec un vêtement classique. Il faisait + de 30° donc j'avais forcément très chaud. Mais plus jamais la sensation d'être agressé par le soleil. ce qui m'a donné plus d'énergie pour marcher. Je ne savais pas qu'avant, quand je randonnai je souffrais de résister à la morsure du soleil. Ou alors il aurait fallu que je me crème toute les heures avec du 50. Retour de vacances, sans "être cramé" et sans avoir mis des litres de crème. Très content !!!

Parfait !

Efficace et élégant, ce tee-shirt de sport est parfait pour jouer au golf en se protégeant du soleil

Super !

T-shirt très léger et confortable, belle couleur, mon mari le porte sans arrêt depuis que je le lui ai offert
