About Us

Welcome to Sinceshe — where comfort meets confidence, every day of the month.

We make leakproof period underwear for women and teens: soft, breathable, reusable underwear with built-in absorbent layers that replace disposable pads and tampons. From heavy-flow nights to light days, swim days to teen first periods, our styles hold from 2 to 5 tampons' worth of flow — so you can move, sleep, and live without checking, changing, or worrying.

Every pair is designed for real life: PFAS-free materials, a stay-dry feel, and a fit that looks and feels like your favorite everyday underwear — not a diaper. Machine washable, made to last hundreds of cycles, and kinder to your wallet and the planet than disposables.

We believe periods shouldn't pause your life. Our goal is simple: reliable protection, honest comfort, and prices that make switching easy.

Move freely. Sleep soundly. Period.
