Let customers speak for us
Qualitativ gut verarbeiteter Anhänger.
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
Geräumige, praktische Tasche. Bin sehr zufrieden damit.
Sieht gut aus, das Dekolleté ist vor Sonne geschützt. Der Po ist leider nicht ganz bedeckt, ich muss immer ein bisschen zuppeln. Aber zum reduzierten Preis perfekt.
Tolles Oberteil das dank den Schnüren individuell angepasst werden kann. Ich habe dasselbe schon in schwarz und bin sehr zufrieden damit
Wunderschöne Decke in bester Qualität, wie beschrieben, wurde das Paket bereits am gleichen Tag auf die Post gebracht. Herzlichen Dank,ich kann Main Design sehr empfehlen!
Dieses Bikinioberteil ist wie eine zweite Haut! Sehr bequem und sitzt super!
Mein absolutes Lieblings Bikinioberteil.
Ich mag den Schnitt sehr und die Wendemöglichkeit ist cool. Die individuelle Schnürung finde ich gut. Habe mir noch ein zweites bestellt :)
Ich bin sehr zufrieden mit dieser Bikinihose. Ich mag den Schnitt, die Hose passt zu vielem und ich finde sie zeitlos.
This is us
We are Tiina and Yvi, two mothers and passionate surfers who founded MAIN Design. Our small Swiss fashion company was born out of the need to find functional and stylish surf bikinis that we were missing. So we started to develop our own designs. MAIN Design stands for sustainable surf and swimwear, especially for the environmentally conscious surfer and mother. Each product is developed with love and care from idea to completion to offer you feel-good swimwear and accessories that make you happy. Our commitment to the environment doesn't stop with our products. With every online sale we donate 1% to Healthy Seas to protect our oceans. Together we create a better future – for ourselves and our children.
Surf Bikinis and Swimsuits for Active Women
Our surf bikinis and swimsuits are specially designed to stay put during movement in the water. Unlike conventional swimwear, they offer secure support, functional cuts, and high wearing comfort – even when surfing, swimming, or stand-up paddling.
Thanks to well-thought-out designs, elastic materials, and sturdy constructions, the pieces stay in place even when you're on the move. At the same time, we prioritize a minimalist, modern design and sustainable materials.
MAIN Design combines functionality with aesthetics – for women who want to move freely in the water without having to worry about their bikini.
Frequently Asked Questions (FAQ)
What advantages do your surf bikinis offer for adventurous women?
Our surf bikinis offer sophisticated lacing systems that ensure optimal hold and prevent unwanted glimpses or slipping necklines. They are also reef-friendly and made from sustainable materials.
How do I avoid unwanted muffin tops with your panties?
Our briefs are equipped with a sophisticated lacing system that ensures a perfect fit and avoids unwanted muffin tops. This allows you to move freely while surfing and swimming.
How do your tops offer more or less support?
Our tops have a sophisticated lacing system that can be individually adjusted. This allows you to adjust the fit to your needs - for more safety and comfort when surfing.
