Trage ihn täglich
Angenehm leichter Stoff, kann problemlos als normales T-Shirt getragen werden
Tolle Farbe!
Bikini Oberteil lässt sich praktisch in der Grösse anpassen
Ein wunderschönes Badekleid aus bequemem Stoff, das gut sitzt. Einfach top! :)
Hübscher Badeanzug, gute Qualität. Der Rest wird sich zeigen nach dem ersten (Sonnen) Baden :-)
Keine Reise mehr ohne dieses Tuch! Unglaublich angenehmes Material. Trocknet ultra schnell nach dem Auswaschen (schneller als mein Trekkingtowel). In allen erdenklichen Weisen tragbar. Verwende es auch als Air-con schutz in Bussen/Unterkünften.
Bestellung und Rücksenden des Bikinis war problemlos.
Danke!
Bedeckt ein bisschen mehr, aber auch nicht zuviel. Ideal für Sport am Strand
Bedeckt was bedeckt werden muss und trotzdem keck.
…sportlich, hält alles wohin es gehört und trotzdem nicht zuviel Stoff. Einfach genial, aja bequem und passt genau :)
Ich bin 172cm und 60kg und habe Grösse S bestellt. Sitzt super und dank doppellagigem Material angenehm zu tragen. Ich bin gespannt, wie er sich zum Surfen anfühlt. Vielen Dank für die schnelle Lieferung!
This bag holds so much! It doesn’t feel heavy on the shoulder, and the strap doesn’t slip off. It’s a very great quality material and so cute. Love this bag so much.
Sehr angenehm zu tragen, nicht nur für's Wasser, auch als Sport-BH oder Top für unter ein Shirt super geeignet!
Ich habe bereits zwei dieser Oberteile in verschiedenen Farben und es verschiebt nichts beim Surfen! Angenehme Träger, einfach zu binden und langlebiges Material!
Kleines handliches praktisches Portemonnaie
Sehr schön verarbeitet

This is MAIN Design
We simply made the perfect surf bikinis ourselves. Why? Because we dreamed of functional, sustainable and beautiful swimwear - and the market couldn't offer us anything that really lasted.
MAIN Design stands for high-quality swimwear with a well-thought-out design that adapts to every wave. We combine minimalist style with maximum support and rely on sustainable materials. Our collections are made for women who love the sea - and for children who want to splash around just as carefree.
Designed for performance. Manufactured with responsibility.
By us, Yvi and Tiina, with great attention to detail and a deep respect for nature.
