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.
