Sustainable swimwear brands made with recycled materials

Most swimsuits are made from synthetics materials like polyurethane, polyester, and nylon that are not biodegradable and historically contribute to plastic waste. But a few sustainable swimwear brands are changing that by making stylish swimsuits from recycled materials.

Sustainable swimwear materials

Two upcycled swimwear fabrics come from ECONYL, which recycles nylon waste into new nylon, and REPREVE, which makes new polyester from recycled plastic bottles. Although the materials will never biodegrade, they can be upcycled again and again.

ECONYL: Upcycled nylon

ECONYL® is a fabric made from waste such as old fishing nets, fabric scraps, carpet flooring and industrial plastic from landfills and oceans. This synthetic plastic waste is regenerated into a nylon fabric that can be used again and again to make new products like swimsuits and workout gear. ECONYL is made by Aquafil, a leading nylon producer.

REPREVE: Upcycled plastic bottles

REPREVE® is a fabric made from recycled plastic bottles. Plastic bottles are upcycled into materials like sustainable swimsuits and trunks, the cloth seats in the electric Ford focus and Patagonia’s fleece. Today more than 16 billion plastic bottles have been recycled into REPREVE fabrics.
