  2. What is a class action lawsuit?

    In a class action, one or more people called "Plaintiffs" or "Class Representatives" sue on behalf of a group of people who have similar claims. In this case, these people together are called a Settlement Class. In a class action, the court resolves the issues for all members of the Settlement Class, except for those who exclude themselves from the Settlement Class. People who do not exclude themselves are called Settlement Class Members. After the parties reached an agreement to settle this case, the Court recognized it as a case that may be treated as a class action for settlement purposes.

  3. What is this lawsuit about?

    The lawsuit involves Thinx Period Underwear and asserts allegations regarding short chain per- and polyfluoroalkyl substances ("PFAS"), Agion anti-microbial treatment, and the organic cotton line of the underwear.

    Thinx denies all of the allegations made in the lawsuit and denies that Thinx did anything improper or unlawful. With respect to PFAS, Thinx confirms that PFAS have never been a part of its product design, and that it will continue to take measures to help ensure that PFAS are not intentionally added to Thinx Period Underwear at any stage of production. The proposed settlement is not an admission of guilt or wrongdoing of any kind by Thinx.

    More information is available in the Complaint.

  4. Why is there a settlement?

    The Court has not decided whether the Plaintiffs or the Defendant should win this case. Instead, both sides agreed to a settlement. The Class Representatives and their attorneys ("Class Counsel") believe that the settlement is in the best interests of the Settlement Class.

  6. What does the settlement provide?

    As part of the settlement, Thinx has agreed to pay $4 million into a cash fund to pay Settlement Class Members who submit valid claims, as well as any court approved attorneys' fees, expenses and service awards to Class Representatives. Thinx has agreed to provide up to an additional $1 million if needed to cover valid claims.

    Settlement Class Members who submit a valid claim have the option to choose either cash reimbursement for past purchases (up to 3 pairs total) or a single-use voucher towards a future purchase of eligible Thinx underwear. The specific options are:

    • Cash reimbursement: You may receive a $7.00 refund for each purchase of up to 3 pairs of Thinx Period Underwear reflected in Thinx's records, or for which you provide a valid proof of purchase (for a total of up to $21.00). Your Claim Form will indicate whether Thinx has a record of your purchases or you need to provide proof of purchase.
    • Cash reimbursement without proof of purchase: You may receive a $3.50 refund for each purchase of up to 3 pairs of Thinx Period Underwear that are not reflected in Thinx's records and for which you do not have proof of purchase (for a total of up to $10.50), but which you attest to purchasing under penalty of perjury.
    • Voucher: You may choose to receive a voucher for a discount of 35% off future purchases of up to $150 of Eligible Voucher Products in a single purchase transaction on the Thinx website ( (maximum discount $52.50).

    If Thinx does not have a record of your past purchases of Thinx Period Underwear, your Claim Form will require you to provide proof of purchase or attest under penalty of perjury to having made the purchases.

    If the net cash fund (including the replenishment amount of up to $1 million) is not sufficient to pay all Valid Claims for cash reimbursement, payments to Settlement Class Members who submit a Valid Claim for cash reimbursement will be prorated and the payment amounts may be reduced. Vouchers will not be counted in calculating the amount of total Valid Claims.

    As part of the settlement, Thinx has also agreed to provide the following non-monetary relief:

    • Thinx will take measures to help ensure that per- and polyfluoroalkyl substances ("PFAS") are not intentionally added to Thinx Period Underwear at any stage of production. These measures will entail maintaining production controls, including material reviews.
    • Thinx will continue to have suppliers of raw materials for Thinx Period Underwear review and sign a Supplier Code of Conduct and Chemical Supplier Agreement, which require suppliers to attest that PFAS are not intentionally added to Thinx Period Underwear.
    • Thinx will disclose the use of anti-microbial treatments, including Agion, and the purpose for which anti-microbial treatments are used, including, if applicable, as odor control treatments, on its website. In addition, Thinx will agree not to refer to the anti-microbial components of Agion as "non-migratory."

  10. Should I get my own lawyer?

    You don't need to hire your own lawyer because Class Counsel is working on your behalf at no additional cost to you. If you want your own lawyer, you will have to pay that lawyer. For example, you can ask your lawyer to appear in Court for you at your own expense if you want someone other than Class Counsel to represent you.

    Back To Top
  11. How will the lawyers be paid?

    Class Counsel will ask the Court for attorneys' fees and expenses totaling up to $1.5 million and will also request service awards of up to $2,500 for each of the five named Plaintiffs (totaling up to $12,500). The Court may award less than the amounts requested by Class Counsel and Plaintiffs, and any money not awarded from these requests will stay in the settlement fund to pay Settlement Class Members. Costs of notice and settlement administration, the Attorneys' Fees and Expenses Payment, and service awards to the named Plaintiffs will be paid out of the $4 million cash fund, if approved by the Court.

  17. How do I object to the settlement?

    If you are a member of the Settlement Class and you do not exclude yourself, you can object to the settlement if you don't like any part of it. You can also object to Class Counsel's request for attorneys' fees and expenses and/or to the service award for the Class Representatives. The Court will consider your views.

    Your objection and supporting papers must be in writing and must include: a caption or title that identifies it as "Objection to Class settlement in Dickens, et al. v. Thinx Inc., Case No. 1:22-cv-4286- JMF;" your name, address, and telephone number; all grounds for the objection, with any factual and legal support for each stated ground; the identity of any witnesses you may call to testify; copies of any exhibits that you intend to introduce into evidence at the Final Approval Hearing; and a statement of whether you intend to appear at the Final Approval Hearing with or without counsel.

    To be timely, the objection must (a) be submitted to the Court either by filing it in person at any location of the United States District Court for the Southern District of New York or by mailing it to 40 Foley Square, New York, NY 10007, and (b) be filed or postmarked on or before April 12, 2023.

    If you do not timely file with the Court a written objection in accordance with these requirements, you will give up any and all rights you may have to object, appear, present witness testimony, and/or submit evidence; be barred from appearing, speaking, or introducing any testimony or evidence at the Final Approval Hearing; be precluded from seeking review of the settlement or Settlement Agreement by appeal or other means; and shall be bound by all the terms of the Settlement Agreement and by all proceedings, orders, and judgments in the lawsuit.

    Class Counsel will file with the Court and post on this website its request for attorneys' fees and expenses and service awards when available.

  18. What's the difference between objecting and excluding myself from the settlement?

    Objecting simply means telling the Court that you don't like something about the settlement. You can object only if you stay in the Settlement Class (i.e., you don't exclude yourself from the settlement). Excluding yourself from the Settlement Class is telling the Court that you don't want to be part of the settlement. If you exclude yourself, you have no basis to object because the case no longer affects you.
