It’s time to catch the wave of sustainable men’s swimwear brands and choose trunks that reflect your values.
Because if we want to protect the ocean instead of pollute it, it’s time we all get on board with sustainable board shorts, speedos, or whatever your swimwear of choice is.
A Quick Dip Into Our Favorite Eco-Friendly Swimwear For Men
Born out of a love of the sea, Fair Harbor makes men’s high-performance swimwear out of 12 plastic water bottles a pop. They’re a go-to for ocean activities and feature styles you’ll love.
The most inclusive sizing award goes to MeUndies, whose sustainable swim trunks go from sizes S to 4XL. With UPF 50+ and eight recycled plastic bottles in each pair, they provide protection for your skin and for the planet.
The unavoidable truth about swimwear is that it’s made from petroleum-based synthetic materials like nylon, spandex, and polyester. These materials are non-biodegradable.
While we’d love to see more men’s natural fiber swimwear, certain performance aspects keep us tied to synthetics (for now).
That’s why the most eco-friendly men’s swimwear brands help regenerate non-biodegradable materials and remove plastic pollution in our oceans simultaneously.

How Did We Choose The Best Sustainable Men’s Swimwear Brands?
There’s no one size fits all when it comes to sustainable fashion, and we know it’s a marathon, not a sprint.
Still, we like to see sustainable men’s swimwear brands hit the ground running (or rather, waves paddling) with a conscious effort to be better.
We have created a set of criteria to look at all areas of the brand’s business and get a holistic look at how they match up.
Global Recycled Standard (GRS), bluesign®, B Corporation (B Corp), Worldwide Responsible Accredited Production (WRAP), Fair Trade Certified, Fair Labor Association (FLA), Forest Stewardship Council (FSC)
Fabrics & Materials:
Organic swimwear for men made from biodegradable materials like ethically-sourced organic cotton and hemp are ideal.
However, that’s just not the reality of quick-drying fabrics. Textile technology isn’t there yet. For that, we still need synthetics—but we can ensure they do minimal damage.
The next best thing available is swimwear made from recyclable fabrics.
Brands that take it a step further by creating swimwear out of recycled materials help remove plastic waste, too.
Plastic-free packaging or that made from recycled materials is something we consider, too.
Carbon Goals & Achievements:
The fashion industry as a whole produces 10% of annual global carbon emissions. It’s no longer enough for brands to sweep their footprint under the carpet.
We want to see them take steps to offset their emissions and reduce the amount they produce.
Responsible brands should be aware of the damaging effects of fast fashion both on the environment and the people that make their clothes.
We want companies to be transparent about their supply chains and ensure their factories are ethical and workers are paid a fair wage for their labor.
Diversity, Equity & Inclusion:
Sustainable fashion shouldn’t just be reserved for the few, but should instead offer inclusive sizing with the same attention to comfort and functionality.
Pay It Forward:
Donating to charities isn’t essential to being a sustainable swimwear brand, as we know it can be expensive to simply operate sustainably.
However, trunks that support charitable giving just wear so much better. We love it when brands donate profits to grassroots projects, charities, and sustainability initiatives, like those listed here.
Closing Thoughts On Sustainable Men’s Swimwear Brands
For us, the most sustainable swimwear brands consider the product’s lifecycle—and you should, too.
Recycling schemes close the loop on swimwear by keeping it in circulation and reducing overall consumption. Take advantage of these whenever you can and don’t buy a new pair of recycled board shorts if you don’t need them.
Even if those shiny new ones are made of recycled plastic bottles, the most sustainable men’s bathing suits are those already in your beach bag.
But if the elastic is getting less than elastic, consider catching the recycled men’s swimwear wave.
