How scores are calculated
Materials (40%): How plastic-free the product is — raw materials, construction, and coatings.
Packaging (20%): Is the product packaged in plastic? Is it recyclable?
Transparency (20%): Does the brand disclose ingredients, sourcing, and manufacturing?
Durability (20%): How long does it last? Longer-lasting products reduce plastic waste over time.
This is a rating of this specific product only — not the company. Other products from this brand may score differently.

Nike's Dri-FIT fabric is 100% polyester — a petroleum-based plastic. Even when made from recycled bottles, polyester sheds microplastic fibers during wear and washing. Worn during exercise when pores are open and sweat increases dermal absorption.
Why We Rated It This Way
100% polyester is 100% plastic. 'Recycled' polyester still sheds the same microplastic fibers as virgin polyester. Nike does not publish PFAS disclosure for their fabrics.
