Sustainable children's swimwear from Switzerland – with a happy factor and a mini-me look

When it comes to children's swimwear , parents have high standards – and rightly so. They want their little ones to not only feel comfortable in and around the water, but also feel well protected and safe. This is precisely why MAIN Design has been offering high-quality children's swimwear for over seven years that not only looks great but also impresses with thoughtful details.

Our story: Children's swimwear with passion for over 7 years

The story of our Swiss children's swimwear began with the birth of our two daughters. Having already designed swimwear for women for several years, we wanted to create beautiful, comfortable, and sustainable swimwear for our children that is skin-friendly and offers optimal sun protection.

For over seven years, we, as moms, designers, and entrepreneurs, have put a lot of love, passion, and expertise into each collection. Our children test every new design before it's included in the collection. This way, we ensure that our swimsuits, bikinis, and UV shirts for children not only look good, but also fit perfectly, are comfortable, and are ready for any adventure.

Sustainable, fair and skin-friendly swimwear for children

At MAIN Design , you'll find exclusively sustainable children's swimwear , handcrafted in Bali under fair conditions. All fabrics are made from recycled materials —for example, old fishing nets and ocean plastic. This is how we actively contribute to protecting our oceans and creating a better future for our children. With every online sale, we also donate a portion to Healthy Seas, a nonprofit organization that helps protect our oceans.

Integrated sun protection: Swimwear for children with UPF50+

Sun protection is especially important for children's swimwear . All of our swimsuits, bikinis, and UV shirts for children feature a built-in UPF 50+ sun protection factor . This ensures sensitive children's skin is optimally protected from harmful UV rays – so kids can play and splash around without worry.

Thanks to the soft, stretchy materials, our children's swimwear sits particularly comfortably on the skin, doesn't chafe, and dries quickly. Perfect for long days by the water!

Mini Me Looks for Mother & Child

The best part: Many of our swimwear designs for children are available in a mini-me look to match the women's swimwear from MAIN Design . Whether it's a mother-daughter matching look or sibling styles – our color-coordinated collections ensure a harmonious look at the beach, at the outdoor pool, or at the lake.
