from 189 reviewsQualitativ 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
Ich wusste nicht, wie sehr ich den Kimono brauche, bis ich ihn gekauft habe. Er ist nun mein Begleiter bei jedem Schwimmbad- und Wellnessbesuch. Er ist super angenehm zu tragen. Ein Essential, auf dass ich nicht mehr verzichten möchte.
Strap is long enough to wear the bag across the body.
Ich habe diese Hose bereits länger in blau und nun auch noch in schwarz gekauft. Strand, Aquapark, Rutschen hat sie alles ohne Probleme überlebt und sieht immer noch gut aus. High waist schnitt ist vorteilhaft und dadurch hält die Hose auch gut.
Baggu hat viele Farben und Muster zur Aiswahl und der Stoff ist für grössere Einkäufe fest genug!
Tut das was es soll - das Bikinioberteil hält! Es ist zwar etwas eng (habe zur Zeit Grösse E), aber es schaut nichts heraus, auch wenn ich freestyle/crawl schwimme (grössere Armbewegungen als bei Brustschwumm). Zudem bequem!
Endlich ein Bikini der auch bei grösseren Brüsten alles dort hält wo es hingehört und super bequem.
Bequemer Schnitt, auch zum Streckenschwimmen super.
Ich bin 172cm und 65kg und habe ein S bestellt, dies sitzt anliegend aber gut.
Allgemein bin ich sehr zufrieden.






We believe in:
Quality in everything we create –
and mindfulness in everything we do.

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.

Sustainability and Fairness
Our sustainable swimwear is made from high-quality, recycled materials - resource-saving, durable and environmentally friendly. We rely on fair production and responsible manufacturing processes so that you can jump into the waves with a good feeling.
