What Are Period Knickers & How Do They Work?

If you've heard the buzz about period knickers but aren't quite sure what they are or how they work, you're not alone. We're here to break it all down — simply, honestly, and without the jargon.

So, What Are Period Knickers?

Period knickers (also known as period pants or period underwear) are reusable underwear designed to absorb your menstrual flow — no pads, no tampons, no mess. They look and feel just like regular underwear, but with a clever built-in 4-layer absorbent system that keeps you dry, comfortable, and leak-free.

How Do They Work?

At ByFullstop., our period knickers use a 4-layer technology that works together to keep you protected:

  • Layer 1 (next to skin): A soft, moisture-wicking inner layer that pulls fluid away from your body, keeping you feeling dry and comfortable.
  • Layer 2: An absorbent core that locks in fluid so it can't escape.
  • Layer 3: A breathable TPU layer that acts as a leak-proof barrier.
  • Layer 4 (outer): A soft, stretchy outer fabric made from 78% Nylon and 22% Spandex — smooth, supportive, and stylish.

Are They Hygienic?

Absolutely. Caring for your period knickers is simple:

  1. Rinse them in cold water after use
  2. Cold machine wash
  3. Hang to dry

Just avoid fabric softener and bleach, as these can break down the absorbent layers over time.

Why Make the Switch?

  • ♻️ Eco-friendly — one pair replaces hundreds of disposable products
