Divine Surfsuit

About Us

MAIN Design GmbH was founded in 2014. As saltwater and surf addicts, we started this line because we both surf & ultimately wanted cute suits that would stay on in the lineup. So we decided to create our own functional surf and active wear without compromising on design. 


In 2018, Tiina and Yvi became a Mom. Since also our girls love the beach and the ocean, we started to design functional saltwater fashion for the little ones. Our next project was born, MAIN Mini. What is more important than protecting the sensitive baby skin from the sun? All our kids wear is made eco-conscious and with UPF50+ sun protection. You can even get matching outfits with your little ones.


Since nature and its wellbeing is most important to us, we produce sustainable and responsibly made products and choose each material with intention and care. We provide fair working conditions for everybody who’s integrated in the process. The fabrics of our eco-conscious collection are made of ECONYL® yarn, a 100% regenerated nylon fibre made from nylon waste otherwise polluting the Earth, like fishing nets, fabric scraps, carpet flooring and industrial
plastic rescued from all over the world. Find more information here

The MAIN Story

«MAIN» is not just a name. Meaning «to play» in indonesian, it stands for everything we believe in and all that we have been inspired by. We want you to chase the waves with us, watch the sunsets together, to smile, laugh and to be playful in everything you do. Come and dive in with us on our saltwater adventures.

We’d love you to follow us on instagram, like us on facebook, share us with friends or get in touch with us by email.

We cherish every feedback in order to help ensure we produce the finest products possible.

We’re excited to hear from you! ♥
With love,
«the MAIN team»
