Thinx Underwear Reviews

Marena S.

“I love my period underwear. These are my favorite for heavier days (I have a medium to heavyish flow)! They are cute and breathable.”


“I have been using Thinx underwear for 6 years now. 6 years! My first four pairs are old, but still do the trick. I now have a nice bundle of period underwear, plus the new ones I just bought to retire my older ones since the lace border has holes. I have not used a pad, or tampon in all that time since having them and I can’t begin to imagine how much garbage I’ve saved from our dumps over the years. If you’re unsure about buying this, don’t be. Take my word for it, you won’t regret. Get yourself a nice kit for heavy and lighter days and your wallet and trash will thank you for it.”
