When the weather’s warm, it’s time for days at the beach, on the boat, and at the pool. And outside by the water, we’re all reminded of how important it is to keep our environment clean. We want to ensure our beachwear is having the lowest environmental impact as possible, so I had to ask, “what are the most sustainable men’s swimwear brands?”

The best sustainable men’s swimwear brands are using organic and recycled materials, low-impact dyes, water-conserving practices and recycled materials for packaging. They use certified textiles like Bluesign and pursue sustainable business certifications like becoming Certified B Corporations. The companies also partner with environmental nonprofits and actively engage their employees in environmental stewardship.

Check out these great sustainable swimwear options from brands that make great products while also trying to minimize their impact on the environment.
