Swimwear is heavy on synthetics, dyes, and water-repellent finishes. We surface the highest-scoring swimwear we have analyzed and explain which fibers and finishes to look at on the label.
Swimwear is one of the categories most consistently flagged for PFAS-based water-repellent finishes. It is also one of the highest microplastic-shedding garments. Recycled-polyester swimwear without DWR finishes is usually the better tradeoff.
These score better on microplastics, biodegradability, or shedding for swimwear. Tap into a material guide for the full breakdown.

Greener Closet treats swimwear as non-toxic when the fiber composition avoids high-shedding synthetics, when there is no evidence of PFAS-based water- or stain-repellent finishes, and when the manufacturing inputs score reasonably on microplastics, half-life, shedding, and energy. Swimwear is one of the categories most consistently flagged for PFAS-based water-repellent finishes. It is also one of the highest microplastic-shedding garments. Recycled-polyester swimwear without DWR finishes is usually the better tradeoff.
Look for Recycled Polyester. These score better on microplastics, biodegradability, or shedding compared with the petroleum-based synthetics that dominate this category.
Be cautious with Polyester, Nylon, Elastane, especially when they appear with stain- or water-resistant finishes. These materials drive most of the score pressure for swimwear.
Each product is scored from the full material label and any available certifications. The scoring weights microplastics at 45%, PFAS at 15%, half-life and biodegradability at 15%, energy at 10%, azo dyes at 10%, and fiber shedding at 5%.
