super Sonnenhut

Ich habe den Hut bisher nur ein Mal getragen und war sehr zufrieden. Da man die Krempe biegen kann, konnte ich sogar auf die Sonnenbrille zum Großteil verzichten. Ich habe mich bestens geschützt gefühlt. und finde ihn auch praktisch zum Transport, da man ihn falten kann

Guten Tag,

vielen Dank für Ihr tolles Feedback! Es freut uns sehr, dass Sie mit dem Sonnenhut zufrieden sind und sich gut geschützt fühlen. Praktisch ist er wirklich – durch die flexible Krempe und die Möglichkeit, ihn zu falten, eignet er sich perfekt für unterwegs.

Freundliche Grüße
Ihr Ker Sun Team
