Is this product suitable for my skin type?

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?

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.

Iets te groot

Ik heb het eenmalig gepast, maar volgens mij is het iets te groot. Ik weet jammer genoeg niet hoe ik dit zou kunnen omruilen voor een kleiner model (medium in plaats van large). Verder lijkt het een heel mooi en degelijk t-shirt!
