19 Fabulous Ethical & Sustainable Swimwear Brands to Wear in 2021

19 Best Ethical & Sustainable Swimwear Brands in 2021

A guide with the best eco-friendly swimwear brands for the conscious beach lovers

We try to recycle, walk places instead of driving, and shorten our showers. However, have you considered the impact of your fashion choices on the environment?

The fashion industry is one of the second-worst polluting industries in the world after the oil industry!

The way clothes are produced is not only harmful to the environment, but it also kills thousands of farmers each year due to chemicals and waste.

So, if that gives you a bad feeling, it’s time to think about making sustainable and ethical fashion choices, and my firm belief is that swimwear is no exception!

Conventional swimwear is made from synthetic fibers like polyester and nylon, and these make up 65% of all fabric production, causing a huge burden on the planet!

Luckily, there are now swimwear brands making use of recycled fibers to produce their suits.

The best part is that there are plenty of affordable sustainable fashion brands that create gorgeous swimwear for those shopping on a budget. Make also sure to check out my guide on the best organic cotton brands.

With summer in full bloom, I want to share with you eco-conscious swimwear brands that attribute to ethical production practices and make shopping an affordable experience.

You can buy mix and match bikinis to one-pieces and bodysuits for women, and swimming shorts for men. 

Thanks to affiliate links, I can pay my bills. If you make a purchase through them, I may receive a small commission (for which I’m deeply grateful) at no cost to you. All opinions are always mine. Merci!

What are eco-friendly bathing suits made of?

When you think of eco-friendly swimwear, you think of organic cotton and natural fibers, but these are a no-go when it comes to swimwear!

This is because cotton swimsuits absorb water which isn’t great for swimming. You don’t want to be dragged down by holding half the ocean in your cotton bathing suits or shorts!

So, what material are swimsuits made of? Sustainable and ethical swimwear is made using recycled synthetic fibers like Econyl and Repreve. Using recycled swimsuit material saves raw materials and energy as well as prevents wastage. 

  • Econyl is regenerated nylon made from waste like fishing nets, old carpets, and industrial plastic from landfills and the ocean. The nylon is recovered and recycled back to its original purity, meaning it has the same properties as virgin nylon. This is one of the best fabrics for swimwear.
  • Repreve® is a polyester fiber made from 100% recycled plastic. This means that this high-performance fiber is gained from recycled plastic bottles that are collected, sorted, baled, cleaned, chopped into flakes, melted, and extruded to make this unique bikini fabric. 

However, brands are becoming more and more creative and inventive. From recycled ocean waste to all-natural fabrics, there are plenty of ways how you can create sustainable swimwear.

Join the fight against throwaway clothing and plastic pollution by buying eco swimwear and beach accessories from the best sustainable brands. 

Let’s take a look at innovative and best sustainable fashion brands to help you find eco-sustainable ethical bathing suits.
