So convenient
I originally started off with one underwear. Then a quietly added two or three more. Now I have around 10 pairs which gets me through an entire week. I love keeping one in my work bag because I get a fresh pair of underwear and absorbency all at once. One time I was late for my period before we went on vacation. I tossed a pair of thinx in my suitcase, just in case. I was lucky to start my cycle the day we were leaving. I tossed my thinx on and had a full 8 hour travel day with 0 issues. I did not have to stop and change disposable products at the airport, buy anything, or leak anywhere. The convenience and true secure feeling I get when I wear these makes me feel that I will probably never go back to disposables ever again.

Cotton starter set
This was the first set I bought from this brand and they were perfect. They are very comfortable and they are perfect even on heavy flow days. I plan on ordering more soon!

I will buy this set again!
Comfortable, stylish, and durable. I really enjoy the new (?) material and fit from my previous pairs of Thinx. I will be buying more of this set!
