Frequently asked questions about period underwear

Period underwear is regular underwear with built-in absorbent layers that replace disposable pads and liners. No inserts needed. Pynpy' uses three layers: a soft bamboo top layer that wicks moisture, an absorbent core that locks it in, and a waterproof layer that prevents leaks.

Yes, for most people. Pynpy' absorbs 5โ€“50ml depending on the style โ€” equivalent to 1โ€“6 regular pads. On heavy days, you may need to change once. We recommend starting on a lighter day to build confidence.

Yes. Every pair is OEKO-TEX certified โ€” independently tested and confirmed free from harmful substances. We use no PFAS (forever chemicals). The bamboo top layer is naturally gentle on sensitive skin, and every production batch is quality tested before shipping.

Rinse in cold water after wearing, then machine wash cold in a laundry bag. Skip fabric softener and bleach. Air dry. With proper care, each pair lasts 2+ years.
