Holds half of a tampon's worth of blood. 

I love THINX and have been wearing them for years. They are super helpful as backup on heavy days, for nighttime, and as the sole protection on light days. Since I would need to change the underwear a few times during a full day at work at the start of my period, I prefer to still use tampons in conjunction with THINX!
