Sustainable children's swimwear from Switzerland – with the happy factor and mini-me look
When it comes to children's swimwear, parents have high standards – and rightly so. The little ones should not only feel comfortable in and around the water, but also be well protected and safe. That is exactly why MAIN Design has been offering high-quality children's swimwear for over 7 years, which not only looks great but also impresses with its 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. Since we had already designed swimwear for women for several years, we also wanted to design beautiful, comfortable and sustainable swimwear for our children, which is skin-friendly and offers optimal protection from the sun.
For over 7 years, as mums, designers and entrepreneurs, we have put a lot of love, passion and know-how into every collection. Our children test every new design before it is added to the collection. This ensures that our swimsuits, bikinis and UV shirts for children not only look good, but also fit perfectly, are comfortable and can keep up with every adventure.

Sustainable, fair and skin-friendly swimwear for children
At MAIN Design, you will find exclusively sustainable children's swimwear, which is produced by hand in Bali under fair conditions. All fabrics are made from recycled materials – such as old fishing nets and marine plastic. This way, we make an active contribution to protecting our oceans and creating a better future for our children. In addition, we donate a portion of every online sale to Healthy Seas to protect our oceans.

Integrated sun protection: swimwear for children with UPF50+
Sun protection is particularly important for children's swimwear. All our swimsuits, bikinis and UV shirts for children are equipped with an integrated sun protection factor of UPF50+. This optimally protects children's sensitive skin from harmful UV rays – so the kids can play and splash around worry-free.
Thanks to the soft, stretchy materials, our children's swimwear feels particularly comfortable on the skin, does not chafe and dries quickly. Perfect for long days by the water!
Mini Me looks for mum & 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 colour-coordinated collections create a harmonious look at the beach, outdoor pool or lake.

Why our customers love our children's swimwear
Our customers particularly appreciate that our children's swimwear is designed in Switzerland and made from high-quality recycled materials. The combination of sustainable production, fair working conditions and lovingly designed styles makes our collection truly special.
Our promise: With us, you get a guaranteed favourite piece and the happy factor included. After all, our kids test it themselves – and are only satisfied when the swimwear can keep up with everything and feels great all around.
