Submit a Claim - Claim Instructions

Claim Forms must be submitted online or postmarked no later than April 12, 2023. By timely submitting the Claim Form, you will be included in the Settlement Class as identified in the Notice and the Class Action Settlement Agreement and Release. If you fail to submit your Claim Form by the deadline, your claim will be rejected, and you will be deemed to have waived all rights to receive a class benefit under the settlement. If you also submit a Request for Exclusion (in other words, if you ask to “opt out” of the Settlement Class), the Claim Form will be deemed invalid.

IMPORTANT: Please read the instructions below before completing the Claim Form.

In completing the Claim Form, you must elect to receive one of two class benefits. You have the option to choose either cash reimbursement for past purchases (up to 3 pairs in total) or a single-use voucher towards a future purchase of Thinx Period Underwear. Thinx Period Underwear means: Cotton Brief, Cotton Bikini, Cotton Thong, Sport, Hiphugger, Hi-Waist, Boyshort, French Cut, Cheeky, and Thong.

  • 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.
  • 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, but which you attest to purchasing under penalty of perjury.
  • Voucher: You may choose to receive a voucher for a discount of 35% off total purchases of up to $150 of Eligible Voucher Products in a single purchase transaction on the Thinx website ( (maximum discount $52.50).

    Vouchers are not transferable, subject to standard terms and conditions, and will be valid for six months from the date of issuance. Vouchers may be used on full-price Eligible Voucher Products only and may not be combined with any other offers, discounts, or promotions. Please click here for a list of Eligible Voucher Products. If Thinx does not have a record of your past purchases of Thinx Period Underwear, you must provide proof of purchase or attest under penalty of perjury to having made the purchases you identify.

For more information about the Settlement benefits available, please review the Notice, the Frequently Asked Questions, and the Settlement Agreement before completing your claim.

To be valid, your Claim Form must be completely and accurately filled out, signed and dated, and must include all requested information. If your Claim Form is incomplete, untimely, illegible, not signed, or contains false information, it may be rejected by the Settlement Administrator.


If you plan to make a claim for cash reimbursement, documentation may be provided to support your claim. Documents should be clear, readable copies, as anything you submit will not be returned to you. Acceptable documentation includes receipts, proof of an online order such as a screenshot, confirmation email from Thinx or another retailer, a credit card statement, or other documents showing the styles purchased, amount of the purchase, the seller, and the purchase date (month/year). You may redact balance information and any transaction information regarding transactions not entered into with Thinx or a third-party retailer of the underwear from your credit card statement(s).

If you are filing online, please have this information ready before you start to file, as your claim will not be saved if you have to come back and finish at a later time. Documents that are uploaded must be less than 20 MB per file and in one of these formats: jpg, jpeg, png, gif, tif, tiff, doc, docx, xls, xlsx, pdf, txt, rtf, or zip. If you are unable to electronically upload a copy of your documents as part of the online Claim Form, you will need to mail a printed Claim Form along with your documentation to the Settlement Administrator.
