Il miglior acquisto dell'estate

Ho un bambino di 3 anni e ho scelto una maglietta costume piuttosto che continuare a mettergli la crema solare ad ogni bagno nel mare. È stata la miglior scelta possibile, appena si bagna rimane fresco anche sotto l'ombrellone, mi sento serena a lasciarlo anche in acqua 5 minuti in più senza ansie di dovergli riapplicare la protezione. Ho una bimba più piccola e quindi lo userò anche con lei, valgono ogni euro speso questi costumi.

Buongiorno,

Grazie di cuore per la sua bellissima recensione.

Siamo felici di sapere che la nostra maglietta anti-UV abbia reso più serene le giornate al mare con il suo bambino! Progettiamo ogni capo con l'obiettivo di offrire una protezione solare efficace UPF50+, comoda e adatta ai più piccoli, anche nelle giornate più calde.

Buona estate a tutta la famiglia e a presto su Ker Sun!
Cordiali saluti,
Il Team Ker Sun

Vêtements parfait

J'ai commandé 3 hauts pour mes petits enfants, un qui n'avait pas de pression au niveau du col n'allait pas à mon petit fils, mais il convenait parfaitement à sa cousine qui l'a récupéré.
Ils ont porté les vêtements lors de chaque baignade, tout est parfait

Sonnenoberteil

Zum Positiven: das Shirt lässt sich dank der Knöpfe leicht an und ausziehen. Meine Tochter trägt es gerne.
Zum negativen: obwohl ich das Shirt eine Nummer größer als die Hose bestellt habe, sitzt es recht eng. Außerdem hatte der Stoff an der Brust leider leicht aufgeriebene Fasern.

Prendas de calidad, entrega algo lenta

Las prendas con de calidad, se debe de tener cuidado con las tallas, según el modelo son más grandes. En Infantil los pantalones van muy apretados, pero las camisetas bien, así que descambié el pantalón y la talla más le ha quedado mejor a la bebé. El servicio de devolución es fácil, el servicio de entrega es algo lento pero llegaron bien. La web se puede mejorar ya que genera dudas en las altas de perfil. Repetiré.

Buenas dias Señor,

Gracias por tomarse el tiempo de dejarnos su opinión.

Lamentamos sinceramente que no haya podido acceder fácilmente a toda la información sobre su pedido.
Para remediarlo, ya le hemos contactado directamente por email con todos los detalles relacionados con su compra.

Trop petit par rapport à la taille indiquée

j'aimerais faire un retour de produit..

Bonjour Madame,

Je suis désolé de voir que la taille ne convient pas à votre enfant. Nous conseillons ce t-shirt (dans la taille 18-24 mois) pour un enfant allant jusqu'à 90cm. Nous avons fait de nombreux tests sur des enfants de cette taille, mais en effet d'autres critères peuvent rentrer en compte et je suis désolé si ça ne convient pas.

Nous proposons les retours gratuits chez Ker Sun, dans le but de palier ce risque.

Comme indiqué sur les fiches produits voici les conditions d'éligibilités aux retours pour un remboursement intégral :

1 - Vous devez avoir réceptionné la commande depuis moins de 15 jours pour nous faire part de votre envie de retourner les produits (par n'importe quel moyen).
2 - Les articles retournés doivent être dans un état neuf et les étiquettes toujours accrochées.

Vous pouvez entre autres faire la demande de retour via la page de retour, disponible ici: https://www.ker-sun.com/pages/retours-et-echanges

Je vous souhaite une belle journée,
Cordialement,
