What it is
Thinx makes reusable period underwear with built-in absorbent technology. Multiple styles (thong, bikini, brief, sleep short) in multiple absorbency levels (light to super) replace disposable pads and tampons. The underwear is machine washable and lasts 2 to 5 years with proper care. The absorbent layer wicks moisture, locks it into an absorbent core, and prevents leaks through a moisture barrier.
Why we picked this
The average person who menstruates uses 11,000 disposable period products in their lifetime, generating roughly 60 kg of non-recyclable waste (pads contain up to 90% plastic). Thinx replaces all of that with washable underwear that works as regular underwear on non-period days. The upfront cost ($30 to $40 per pair, 5 to 7 pairs needed) is higher than a box of pads, but the 2 to 5 year lifespan makes it cheaper within 6 to 12 months. More importantly, it eliminates the monthly purchase cycle, packaging waste, and the anxiety of running out.
Key takeaways
- The average menstruating person uses 11,000 disposable products in their lifetime, generating roughly 60 kg of landfill waste containing up to 90% plastic.
- A set of 5 to 7 Thinx pairs costs $150 to $280 upfront but replaces $50 to $100 per year in disposable purchases, breaking even within 6 to 18 months.
- Reusable period products eliminate exposure to the fragrances, bleaching chemicals, and pesticide residues found in conventional disposable pads and tampons.
