fällt leider viel zu klein

Ich habe 2 Boardshorts in M-L bestellt. Eine davon passt prima, diese hier ist leider viel zu eng.

Hallo Thomas,

vielen Dank für deine Bewertung zu unserer Boardshorts von Olaian.

Wir bedauern natürlich sehr, dass du unzufriede mit der Größenwahl bist. Sind aber auch froh, dass die Größere Größe passt.

Leider fallen die Produkte von Olaian in der Tat kleiner aus.

Ich wünsche dir viel Spaß mit deiner Boardshorts und einen schönen Tag!

Mit sportlichen Grüßen

Déçu par ce produit

Il y a loin de l'image à la réalité, surtout en ce qui concerne la coupe ! Bref, un produit à 5 euros dans un supermarché.
