Einfach, schlicht, schön...

... und hält, was es verspricht. Auch bei kleinen Brüsten top - zum Schwimmen, als Top unter dem Kleid, egal ob im Meer, See oder Fluss. Ich bin Fan! Die Pads sind für mich unnötig, da diese an mir unnatürlich aussehen und v.a. länger nass bleiben. Aber diese sind einfach herausnehmbar.

Main Design

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.
