The Top Ethical Swimwear Brands: 7 Eco Friendly Swimsuit Brands

Summer is heating up and so are our picks for the best, eco-friendly swimwear. We know shopping for swimwear is hard. 

Finding something that makes you feel confident while being both cute and comfortable isn’t easy. Add in trying to find the perfect piece that is also environmentally friendly and ethically made and you may find yourself giving up. That’s why we’ve compiled our favorite sustainable swimwear brands for your summer needs.

The top ethical swimwear brands for Summer 2024:

1. Outerknown

What Outerknown lacks in variety of their selection, they make up for in quality and cuteness. They offer surf suits, crop top bikini tops (that further act as rash guards), and several different colors of board shorts. They even have a beach towel available to buy. If you are an avid surfer, Outerknown is definitely the brand for you.

Beyond their vast selection of clothing to pick from, we cannot ignore their impressive commitment to sustainability. Outerknown sources materials from 8 facilities running on renewable energy, and they’ve moved 67% of their supply chain in order to better support laborers by only working with suppliers who prioritize human rights. They also have partnered with Bergman Rivera, which supports farmers implementing Regenerative Organic CertifiedTM practices, creating more sustainable, eco-friendly farmland.

2. prAna

If you are looking for a full beach/pool day outfit, look no further than prAna. prAna offers versatile swimsuits (including one pieces, swim skirts, bikinis, and more) as well as beach pants and cover-ups. Their ethical and sustainable swimwear come in a variety of styles (tie-up, high-waisted, open-back), as well as an array of colors and prints. If you choose prAna for your swimwear needs, you don’t have to sacrifice sexy for sustainable.

PrAna offers an incredibly detailed report on what they are doing to reduce their environmental impact. On their website, they offer an in-depth look into their supply chain, providing information on their factories, the locations of their factories, and their certifications and their awards. They also have information dedicated to their social responsibility, which provides facts on how they protect their workers through a program based on a Code of Conduct and their partnership with the Fair Labor Association.

Further, they are committed to circularity. Through a Renewed Apparel Program, they are extending the life of their clothing. They take back used clothing and repair/mend it, then resell. By doing so, they have saved over 50,000 pounds of garment waste from landfills since 2016.

3. Patagonia

Our next pick is Patagonia. You may know Patagonia for their expansive outdoor clothing and accessory line. However, what you may not realize is that they have a swimwear collection that will make you look and feel your best. From dropped neckline one pieces to stylish board shorts to supportive bikini tops: Patagonia can meet all your summer swimwear needs.

Besides their vast clothing selection, one of our favorite things about Patagonia is their commitment to proper working conditions and environmentally friendly sourcing. They disclose both the name, location, and conditions of every one of their facilities for complete traceability. Further, over ⅔ of their manufacturers are Fair Trade certified.

Another cool aspect of Patagonia’s outreach is their commitment to activism. On their website, they have a Take Action tab, offering links to several different campaigns concerning human rights and environmentalism. Each link takes you to a page discussing how you can help. Patagonia also has instituted a new policy in which they funnel all of their profits into environmental non-profits, meaning they have expanded beyond their own ecological footprint and are actively working to help others improve their impact on the environment, as well.

Why should you shop sustainably?

You may be wondering why you should shop sustainably when it can be cheaper and simpler to pop onto sites like Shein and ASOS. Finding cute, reasonably-priced clothing that is ethically sourced can sound like a lot of time and effort. That’s why we are doing the work for you.

Using eco-friendly, ethical brands is crucial in creating higher standards for the fashion industry. It’s easy to get tricked into thinking that your impact as one person doesn’t matter. However, each person that commits to shopping sustainably can substantially reduce the amount of waste and negative environmental impacts caused by fast fashion. Additionally, your sustainable choices can create a “neighbor effect”, in which you influence your friends and family to shop ethically, too.

Further, by only supporting brands that provide their garment workers with a livable wage and proper working conditions, you are forcing other brands to conform to more ethical practices. One person forgoing fast fashion can be the difference of hundreds of pounds of clothing being recycled instead of wasted, or a garment worker being able to have a safe workplace. Your fashion habits matter.

Why care about eco-friendly swimwear?

While we all love the sleek feel of water-repellent swimwear, conventional swimwear is made from synthetic materials derived from plastic, making it harmful to the environment. Further, these bathing suits are not biodegradable and often end up in landfills, which are then dumped back into the ocean. 

This means your swimwear often ends up polluting the bodies of water it is meant for! When you don’t wear ethical swimwear, you contribute to the millions of tons of waste polluting our world. Just washing synthetically made swimwear contributes to microplastics being released into water systems. That’s why even when it comes to wearing swimwear made from recycled polyester, you need to be mindful of how you care for your clothing. That may mean washing swimsuits made from recycled polyester in a microplastic bag.

What should you look for when shopping eco friendly swimsuit brands?

Ethical manufacturing and ethical production are so important when it comes to shopping for sustainable swimsuits. This summer when you’re looking for that perfect bikini top or cover-up, you want to shop for brands that prioritize eco-friendly and ethical practices. 

Look for products that boast tags saying: made from recycled materials, including recycled plastic and recycled nylon. Otherwise, we will end up with no clean, fresh bodies of water to swim in.
