about us

MAIN Design was founded in Bali in 2014. As saltwater and surf addicts, we often got frustrated by the nonexistence of bikinis which actually stay on during our surf sessions. So we decided to create our own functional surf and active wear without compromising on design. What started as a fun little project, providing us and our friends with the bikinis, became our passion. We try to do our best possible designing active wear that stays on, no matter which sports you love. All our products are developed and designed in Bali. Our label is born out of our simple love of travel, adventures, fun and friendship. All these experiences inspire us to create every year’s collection which is devoted to style, quality, form and functionality.


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. The fabrics of our eco-conscious collection are made of ECONYL®, a 100% regenerated nylon fibre made from recovered fishing nets and other nylon waste. Find more information here


«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»
