How We Found The Best Eco-Friendly Men’s Swimwear Brands

When searching for eco-friendly men’s swimwear brands, it’s crucial to consider materials, certifications, supply chain and labor practices, carbon commitments and green practices, and community and charitable giving.

Materials

While natural fibers like organic cotton and hemp are compostable, they don’t have the quick-drying and non-absorbing qualities needed for most swimwear. Therefore, synthetic fabrics are necessary, but recycled alternatives such as swim trunks made from recycled plastic bottles or upcycled marine waste like fishing nets can keep additional plastic pollution from entering the ocean. Brands that use recycled materials and have certifications such as Global Organic Textile Standard (GOTS), bluesign®, Global Recycled Standard (GRS), Forest Stewardship Council (FSC), and Organic Cotton Standard (OCS) are preferred.

Supply Chain & Labor Practices

Ethical production methods that enhance human rights are essential. Brands that are transparent, have fair labor practices, and hold third-party certifications such as Fair Labor Association (FLA), B Corporation, and Fair Trade are preferred. For brands without this information, direct inquiries are made to ensure ethical practices.

Carbon Commitments & Green Practices

Brands that compensate for and reduce carbon emissions through upcycled plastic waste, circularity initiatives, textile waste practices, carbon offset programs, renewable energy, and low-waste/plastic-free packaging are preferred.

Community & Charitable Giving

Brands that give back to their local communities, support nonprofits, and organize environmental clean-up events are preferred.

Final Thoughts On Environmentally Friendly Men’s Swimsuits

Sustainable men’s swimwear that’s affordable, durable, comfortable, and keeps plastic out of the ocean is the perfect beach day essential. However, it’s important to remember that the most sustainable swim trunks are those already in the drawer. If they still have some dives left in them, keep using them. Additionally, online thrift stores offer affordable eco-friendly board shorts in just the right size.
