Whenever you go to the beach, there are a few specific things you need to bring to make your trip fun and unforgettable. One of the most important things you should not forget to pack in your suitcase is your swimsuit. 

Whether you enjoy swimming in the ocean or the pool or simply prefer relaxing on your beach towel, swimwear is absolutely essential to have. 

Sometimes, it can be tricky to find a good-quality swimsuit. But as an adult, once you have found one or two you like, you can usually enjoy them for a while. For kids’ swimwear, it is a little different as children grow so quickly! You have to buy new swim shorts or bikini sets for your kids a lot more regularly! 

Plus, as an eco-conscious parent, you might want to purchase swimsuits that will not harm the planet. This can be difficult because they are all made of synthetic materials, and we know how bad plastic is for our environment. 

So if you are looking for new eco-friendly swimwear for your children this year, this article is for you! We have selected 10 sustainable brands selling kids’ swimsuits so that you and your family can create happy memories on your next trip to the beach! 


When we see kids’ swimsuits costing as little as a few dollars at the store, we can easily be tempted to go for the cheap option. However, with such a low price tag, swimwear cannot be made to last or produced under ethical conditions. 

So try to avoid fast fashion brands as much as possible, and support an ethical company that pays its workers a fair wage, treats them well and provides them with healthy, safe working conditions. Remember that when something is too cheap, someone in the supply chain is paying the price. 

You also don’t want your child to lose his/her swimsuit while having fun with friends. So investing in quality is the way to go to make sure the piece will last. 

Finally, try to support brands that have taken steps to minimize their environmental footprint, and choose swimwear made from eco-friendly materials. 


Unfortunately, it is almost impossible to avoid synthetic materials when buying swimsuits as they have to be stretchy. Natural fabrics would also not last long if used in salt water or chlorine-filled swimming pools.  

Thankfully, there are sustainable alternatives to polyester and nylon, which are what most swimsuits on the market are made of. For instance, recycled polyester and recycled nylon, produced from plastic water bottles or nylon fishing nets, are great options! 

Buying swimwear made with these materials helps divert plastic waste from landfills and oceans and encourages manufacturers to stop using virgin petroleum-based materials to create new products.  


1) Kampos

Size Range: 4 To 12 Years

Materials: Recycled Nylon, Recycled Polyester

Price Range: $90-112

KAMPOS redefines luxury by transforming waste found in the ocean into high-quality swimwear.

The bikinis feature a classic cut with a triangle bikini top and a tie-side bottom. 

While the boys’ swim shorts are all made with 100% recycled plastic bottles, the girls’ collection is produced using recycled fishing nets and other nylon waste. 

KAMPOS uses recycled packaging that is also 100% recyclable and FSC-certified. It also donates part of its profits to the Coral Conservation Project, an initiative launched to protect and restore coral reefs in the Maldives. 

The brand is a certified B Corporation, and in 2022, it was named Best for the World™ in the Environment and Community categories. Plus, KAMPOS received the Butterfly Mark accreditation, which identifies luxury brands meeting the highest standards of environmental performance.

Not only that but the original fabric is also produced from plastic waste dredged from the sea, like fishing nets, as well as fabric scraps, carpet flooring, and industrial plastic waste from landfills and oceans. 

We also love that Elle Evans chooses to make each piece to order, which means that it is only produced when you buy it. This helps reduce fabric waste to a minimum, and the company even reuses smaller scraps and turns them into frills or straps for other swimsuits!  

Elle Evans works with a digital printer that uses water-based, non-toxic inks and makes sure to never discard inks down the drain. It also ships its products through carbon-neutral couriers.

The company also donates 1% of all its sales to the Healthy Seas Initiative, which is the organization that collects the nylon waste used in Elle Evans’ collections.
