Whether you’re heading out for an annual beach vacation or you go swimming every day, you’ll need a durable, comfy swimsuit that’s suitable for water sports and adventures. We always recommend purchasing sustainable gear when possible, and swimwear is no exception. Sustainable swimwear is good for the planet – often made with organic, recyclable, and eco-friendly materials – and is built to last for all of your water sports and adventures. Swimsuits also make great gifts for surfers or anyone who loves the outdoors. We’ve created this guide to help you learn more about best sustainable swimwear brands to consider when buying your next eco-friendly swimsuit.

What Makes a Swimwear Brand “Sustainable”?

“Sustainability” is a word that’s thrown out a lot in the outdoor gear and fashion world…but what does it actually mean? To us, sustainability consists of three main components:

  • Recycled and/or eco-friendly materials – Are the products made of recycled or eco-friendly materials? Do the companies take efforts to reduce greenhouse gases in production?
  • Ethical manufacturing practices – Does the company pay fair wages and practice ethical employment? Are factory conditions safe and comfortable for workers? Are factories audited regularly for compliance?
  • Low-waste shipping and distribution – Do companies reduce single-use packaging? Do they utilize compostable materials where possible? Do they do anything to offset climate impacts of shipping?

Some of the most popular recycled/eco-friendly swim fabrics you’ll see include:


And these are some of the certifications you should look for the ensure these brands are accountable for their sustainability promises:

  • Climate Neutral Certified
  • OEKO-Tex 100
  • Fair Trade Certified
  • AS8000

A Note on Greenwashing: Many companies out there claim to have “sustainable” practices but actually don’t. We tried our best to weed out the companies who don’t have transparent practices or proof behind their statements. However, the degree to which these companies follow through on sustainability measures is difficult to measure and compare. Use your own research and judgment to make purchasing decisions!
