We know, this sounds pretty weird. Not weird, tho. Just awesome.

THINX can back up or replace tampons, pads, cups, or even sea sponges (if you're into that), depending on your flow.

They absorb up to 2 tampons' worth of blood, yet they look and feel like a regular pair of underwear.

Try 'em' risk free. If you're not period-ing better within 60 days, we'll give your $$ back.
