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.

Synthetic activewear is worn against your skin for hours, often while sweating. Sweat dramatically increases microplastic and chemical absorption through the skin. The Align Pant is made from Luon fabric — a proprietary blend of nylon and elastane, both petroleum-based plastics.
Why We Rated It This Way
100% synthetic plastic fabric worn against skin during exercise. No natural fiber content. Lululemon does not publish full chemical disclosure for their fabrics.
Chemical & Health Analysis
Each chemical of concern is broken down below — what it is, where it comes from in this product, what it does to the body, and who is most at risk.
Nylon-6 microfibers
Nylon fabric shed during wear and washing
Synthetic fabrics shed microplastic fibers during wear and washing. Worn against skin during exercise, microplastics and chemical additives can be absorbed transdermally.
