What is Thinx?

Thinx sells reusable underwear designed to absorb menstrual flow and light bladder leaks. Wikipedia names Radha Agrawal, Miki Agrawal and Antonia Dunbar as founders and gives New York City as its headquarters. The founding year is stated inconsistently, with the infobox giving 2014 and the article text 2011, so it is shown here as 2011 with that caveat.

Ownership

Kimberly-Clark acquired a majority stake in Thinx in February 2022, following a minority investment in 2019. The consumer goods group is therefore the current parent.

Products and positioning

According to the brand's website, the range covers period underwear in styles such as hiphugger, brief, hi-waist, boyshort and bikini, bladder-leak underwear, youth sizes for teens, overnight and 3-in-1 options and saver sets. Sizing is described as inclusive, up to 4X. The brand states that its absorbent layers hold up to 12 regular tampons' worth of flow and notes that individual results may vary. Wikipedia also lists organic tampons and a reusable tampon applicator, and a BTWN line for teens and tweens.

Business model and distribution

Thinx sells direct through its own online store, which offers a 45-day trial and free returns on non-final-sale items, and ships to a list of countries that includes the United Kingdom, Canada, Australia and much of Europe. It also reached mass retail: Wikipedia reports that products were placed in Target and Walmart during the tenure of former CEO Maria Molland.

  • Owner: Kimberly-Clark (majority, since 2022)
  • Core product: reusable period underwear
  • Channels: direct to consumer and mass retail

Why it matters

Thinx helped bring period underwear from a niche idea into mainstream retail and a major consumer goods group. It is a reference case for how a direct-to-consumer intimates brand can be absorbed into a larger health and hygiene portfolio.
