Plus-Size Period Underwear

Our plus-size period panties use Modibodi’s patented 3-layer technology for powerful, breathable leak protection. A moisture-wicking top layer keeps you dry. The absorbent middle locks in periods, sweat, and discharge. And the leak-proof barrier keeps it all in, without bulk. Every pair is made from OEKO-TEX certified fabrics and is 100% free from PFAS, nanotech, and other harmful chemicals. Learn more about our PFAS-free materials.
