More than 12 billion pads and tampons are thrown out every year, and the average person with a period uses 11,000 pads, tampons, and panty liners in their lifetime - that's a lot of landfill waste! 

Now, getting your first period doesn't have to be scary, and you don't have to commit to creating mountains of waste. These period underwear are made with organic cotton and THINX signature tech that absorbs your flow, controls odor, helps prevents leaks, and keeps you fresh ‘n’ dry — all without feeling bulky or wet.

This box contains a mix of 3 styles of THINX (BTWN) absorbent organic cotton period underwear, designed for young beginners.  Each box contains one brief (pink and red dot pattern), one bikini (solid red), and one shorty (solid blue), to last your entire cycle.

Use and care

Each pair holds up to 3 teaspoons. Use as a replacement on lighter days, or as a backup to other products on heavier days.

For a heavier flow, we also carry other varieties of THINX with greater capacity, in a wide range of sizes. You can also try out a menstrual cup, when you're feeling ready! 

Wash and care

Between uses, rinse, throw in the washing machine (cold or warm water), and hang dry. No bleach, fabric softener, or irons.


THINX (BTWN) are true to classic sizing for girls’ underwear and clothing.
