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?

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.

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.

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.

Lieferung top, Armstulpen qualitativ nicht gut

Leider löst sich nach ca 4 Wochen Tragen (nicht mal täglich und auch nur jeweils 1 Stunde am Tag) das Logo vom Ärmel. Außerdem ist die Größenangabe echt schwierig. Nach dieser kurzen tragezeit leiern die Stulpen leider schon aus und rutschen andauernd runter (auch wenn ich sie enger einstelle oben). Evtl. kann es ja eine fehlerhafte Produktion sein?

Manchettes anti UV

Protège du soleil mais la fixation en haut n’est pas très pratique, je dirai même soit çà serre normalement et alors la manchette ne tient pas bien et fait l’accordéon soit on la serre bien et alors elle gêne le haut du bras

Super pratiques et confortables.

Parfait dans le sac de randonnée pour les moments les plus exposés de la journée. En plus elles ne tiennent pas trop chaud !
J'hésitais entre les tailles M et L, car d'après mes mesures j'étais entre les deux. J'ai fini par prendre la taille M qui était le bon choix, je dois même sérer un peu les élastiques. Les manches vont de mon poignet jusqu'au haut de mon bras et les recouvrent donc bien, même associé à un T-shirt avec des manches très courtes (j'avais mesuré autour du biceps comme sur le dessin, d'où le problème de taille. Je mesure 1,65 m).

fijne armstukken

veel gebruikt in deze zonnige zomer. Een tweede set (samen met een lange rok ook van Ker Sun) gebruikt voor mijn onderbenen omdat ik juist daar het meeste last heb van zonne allergie. Ik kom, zeker overdag, zo min mogelijk/zo kort mogelijk in de zon. De laatste weken geen nieuwe uitbarsting gehad hoewel de huid gevoelig/schilferig blijft. (Voor de onderbenen zou een grotere maat beter zijn geweest.)
Het draagt fijn, zachte stof voor een gevoelige huid

Les bras au frais

Utiliser sur 3 sorties vélo entre 4h et 5h. Alors qu il fait chaud, le tissu apporte comme une fraicheur, que je ne peux expliquer. Plus de soleil qui tape sur mes bras, un bonheur.
Ce qui serait top c est un maillot de velo anti uv 😉

Arm UV protection

The arm protection suits well, when you put them on. During some sport activity they can slide a bit down on top, but there is a built-in strap you can tighten. After a couple of usage you need to tighten it a bit more to stay. All together I am happy with them. Although they seem warm at Summer, but it feels somehow less warm if the sun shines not directly to your skin.

Verbesserungsvorschlag

Der Armverschluss oben passt nicht unbedingt und ist dann hinderlich.
Er sollte entweder stärker verstellbar sein ( in meinem Fall bei Größe S noch kürzer einzustellen), besser jedoch durch ein einmalig verstellbares Gummi ersetzt werden, das weniger aufträgt.
Ich ersetze den Verschluss aktuell durch flexiblere Haargummis.
