Eco friendly swimwear ethically made for women & men

Eco friendly swimwear

Are you looking for sustainably made swimwear? If so, you’re in the right place. We’ve researched and collated some of the best eco friendly brands that produce swimming costumes for women, and swimming trunks for men.

What materials are used to make eco-friendly swimwear?

If you’ve ever worn a regular swimming costume or trunks you’ll know it has a certain, somewhat stretchy, feel to it – or you might like to call it plasticky – that’s because it is.  

Regular swimwear is typically made from virgin plastics, such as nylon i.e. plastic that has been produced using fossil fuels, which is harmful for the planet. 

Whereas the brands we have listed in this article have all used recycled fabrics and/or recycled plastics to create their product range, which means you still get the same material feel you’re used to in swimwear, but without any of the fast-fashion guilt. 

The key innovative fabric that has been created specifically to cater for eco-friendly swimwear which you should look out for is ECONYL®. 

This is because ECONYL® is made using regenerated nylon plastic waste from items such as discarded ocean fishing nets, old fabric scraps and carpet offcuts. ECONYL® has been designed with circular economy principles in mind, meaning that it can be recycled and reused multiple times, thus reducing waste.

How should you wash eco-friendly swimwear?

To help reduce excess energy consumption it’s always advisable to hand wash items of clothing. If you do want to use a washing machine, that’s fine too. Ideally, if using a washing machine, ECONYL® fabric is best washed on a cold water setting or very low heat.
