In February 2025, a federal court in Florida dismissed the class action lawsuit against Lululemon over its Be Planet sustainability campaign. The ruling was about legal standing. The court never addressed the central question the plaintiffs raised: is recycled polyester bad?
The allegations remain on the public record. A peer-reviewed study published in January 2026 found that recycled polyester fibers shed up to 6.2 times more microplastics than virgin polyester. The gap between what recycled polyester marketing implies and what the material actually delivers has not been resolved by any court. For brand founders building their 2027 lines, the question is not academic.
What did Lululemon's Be Planet campaign claim?
Lululemon launched the Be Planet campaign in October 2020. On its sustainability page, the company stated that it is committed to making products and taking actions that "avoid environmental harm and contribute to restoring a healthy planet."
The class action, filed in July 2024, alleged that this messaging creates "the general, express, and implied impression in consumers' minds" that Lululemon products help the environment. The plaintiffs argued that this impression is misleading given the material composition of the products themselves.
According to the complaint summary on ClassAction.org, consumers alleged they were persuaded to pay a "premium price" for Lululemon products based on the Be Planet marketing. The case targeted what plaintiffs called a contradiction between brand messaging and product reality.
What do Lululemon's product pages actually show?
According to company reporting cited by Forbes, polyester represents 33 percent of Lululemon's material mix by volume. Nylon accounts for another 30 percent. That means more than 60 percent of the materials Lululemon purchases are derived from fossil fuels.
The class action complaint, summarized by Sourcing Journal, alleged that "polyester and nylon represent over 60% of the company's material mix, and they release significant amounts of microplastics."
Lululemon has made progress on recycled content. According to Trellis reporting, the brand sourced 77 percent recycled polyester in 2024, exceeding its 2025 target by a year. But only 11 percent of its nylon comes from recycled or renewable sources. The company has also revised its 2030 preferred materials target down from 100 percent to 90 percent.
What is the gap between the claim and the product?
The class action alleged three specific issues with recycled polyester that the Be Planet marketing did not disclose:
- Recycled polyester is energy intensive to manufacture. Melting down plastic bottles and extruding new fiber requires significant energy input. The recycling process does not eliminate the material's environmental footprint.
- Recycled polyester does not biodegrade. It is chemically identical to virgin polyester. In a landfill or ocean, it persists for hundreds of years.
- Recycled polyester still sheds microplastics. The recycled origin of the fiber does not change its shedding behavior during washing. In fact, recent peer-reviewed research suggests it may shed more.
These allegations were not contested by the court. The dismissal, as reported by the National Law Review, was based on Article III standing. The court found that "blanket assertions are insufficient to constitute an economic injury."
In plain language: the plaintiffs could not connect the marketing to a specific product they bought and show they were financially harmed. The court did not rule on whether the marketing claims were accurate or misleading.
Does recycled polyester shed more microplastics than virgin polyester?
Yes, according to the most recent peer-reviewed research. A study published in January 2026 in Environmental Science & Technology, available through PubMed, found that mechanically recycled textiles are a significant source of microplastic fiber emissions.
The University of Borås research found that fabrics with fibers recycled twice released approximately 4.3 times more microplastic fibers than virgin polyester. Fabrics with fibers recycled three times released approximately 6.2 times more. The mechanical recycling process shortens fiber length and increases surface area, both factors that accelerate shedding.
A separate study commissioned by the Changing Markets Foundation in December 2025 tested 51 garments from major brands including Adidas, H&M, Nike, Shein, and Zara. The laboratory testing, conducted by the Microplastic Research Group at Çukurova University in Turkey, found that recycled polyester garments released 55 percent more microplastic particles during washing compared to virgin polyester garments. The particles shed from recycled fabrics were also nearly 20 percent smaller, meaning they travel farther through wastewater systems and penetrate more deeply into biological systems.
As covered in the plastic-free activewear guide, the shedding question is not new. What is new is the scale of the disparity now being documented in peer-reviewed journals.
Why does this matter for the question of whether recycled polyester is bad?
The dismissal leaves the underlying question unanswered. A brand founder reading this case might conclude that recycled polyester marketing is legally safe because the lawsuit was thrown out. That would be a misreading.
The court found a procedural defect in the plaintiffs' case. It did not validate Lululemon's marketing. According to Arnold & Porter analysis, the ruling sets a precedent requiring future plaintiffs to tie specific product purchases to specific marketing claims. It does not establish that recycled polyester claims are accurate.
The Canada Competition Bureau, as reported by Business of Fashion, opened a separate investigation into the same Be Planet campaign in May 2024. That investigation remains ongoing as of September 2026.
What does the EU regulatory timeline mean for recycled polyester claims?
For brands selling into Europe, the context is tighter. The EU's Directive 2024/825, known as the ECGT, takes effect on September 27, 2026, according to Regonance. That is eight days from today. There is no transition period. Claims that were acceptable on September 26 may be unlawful on September 27.
According to Carbonfact's analysis of the directive, generic environmental claims without specific, verifiable evidence will be prohibited. The directive explicitly bans vague language like "eco-friendly" or "sustainable" unless backed by recognized evidence. Self-created eco-labels are also prohibited.
The amended Unfair Commercial Practices Directive, per GreenStitch analysis, allows for fines of up to 4 percent of annual turnover for widespread infringements. Individual Member States may set higher thresholds.
For a brand claiming that its recycled polyester products are environmentally beneficial, the EU enforcement environment now requires proof. A recycled content percentage is not proof of environmental benefit if the recycled material sheds more microplastics than the virgin alternative.
Is the post-consumer versus post-industrial distinction disclosed?
One issue the class action did not specifically address is the source of recycled polyester. According to Duvaltex industry analysis, post-consumer recycled content comes from products that reached end of life after consumer use. Post-industrial recycled content comes from manufacturing waste that never reached consumers.
Post-industrial recycled content is cheaper and cleaner to process because it has not been contaminated by consumer use. But it does not divert waste from the consumer stream. A bottle that becomes a shirt represents genuine diversion. A factory scrap that gets reprocessed into fiber was never going to reach a landfill anyway.
According to the Changing Markets Foundation report, only around 2 percent of recycled polyester comes from textile-to-textile recycling systems. The rest is downcycled from beverage containers. This means the "recycled" claim, while technically accurate, often obscures what is actually being recycled and where it came from.
As DeadSoxy's analysis notes, brands that use post-consumer recycled polyester typically state this explicitly, while generic "recycled polyester" labels normally indicate pre-consumer material. The distinction matters for environmental impact, but most brands do not disclose it clearly.
What are other brands in the category doing?
Some activewear brands have moved away from recycled polyester marketing and toward third-party verified claims or natural fibers.
Patagonia has invested in transparency around its microfiber impact. According to NRDC reporting, Patagonia earned a B grade on the PFAS scorecard, the highest among outdoor brands, with a commitment to phase out all PFAS by 2024. The company also publishes information on its fiber choices and their environmental tradeoffs, including microfiber shedding research.
Good On You rates multiple polyester-free activewear brands that have shifted entirely to natural fibers like organic cotton, merino wool, or Tencel lyocell. These brands avoid the microplastic shedding question altogether by not using synthetic fibers.
Levi Strauss earned an A+ on the NRDC PFAS scorecard for already eliminating forever chemicals from its supply chain. While this rating is specific to PFAS rather than microplastics, it demonstrates that proactive elimination, rather than incremental recycled-content targets, is achievable at scale.
The contrast matters. Lululemon has set a target of sourcing 90 percent preferred materials by 2030. Other brands have already reached or exceeded similar milestones by choosing different materials entirely.
What should a brand founder ask their supplier?
If you are sourcing recycled polyester for your 2027 or 2028 line, the Lululemon case and the January 2026 shedding research offer a checklist of questions that go beyond the standard certification inquiry:
"Can you provide microfiber shedding test results for this fabric using a recognized standard like AATCC TM212 or ISO 4484?"
"How many times has this fiber been mechanically recycled? The University of Borås data shows shedding increases with each recycling cycle."
"What percentage of the recycled content is post-consumer versus post-industrial?"
"Has this fabric been tested for PFAS using total organic fluorine screening?"
"If we market this as recycled polyester, what specific evidence can we cite if challenged by a regulator under the EU ECGT?"
"Does your GRS or RCS certification cover the finished garment or only the fabric input?"
The questions are specific because regulators are getting specific. The era of vague sustainability language is ending. What remains is proof.
What does this mean for brands building lines in 2027?
The Lululemon class action dismissal does not mean recycled polyester marketing is safe. It means one group of plaintiffs could not prove standing in one federal court.
The Canada Competition Bureau investigation is ongoing. The EU ECGT enforcement begins in eight days. State-level PFAS regulations in New York, California, and Connecticut already restrict what can be sold and what must be disclosed. And the peer-reviewed shedding data now shows recycled polyester performs worse, not better, on microplastic emissions.
For a brand founder, the practical question is not whether recycled polyester is bad in some abstract sense. It is whether the marketing claims you make can withstand scrutiny when the regulator or the plaintiff finds a procedural path to challenge them.
OHZEHN-TEX(TM) licensees building plant-based performance lines can sidestep the entire debate by starting with natural fibers that do not shed synthetic microplastics and do not require recycled-content disclosure gymnastics.
The dismissal of one lawsuit does not close the question. It leaves it open for the next case, the next regulator, the next audit. The shedding data is now public. The enforcement date is eight days away. The gap between the claim and the product is documented.
