Does Period Underwear Wear Out?

Yes. Like any underwear, it wears out over time. Each wear and each wash adds a little wear to the fabric, the bands and the layers.

Good care slows this down. So does having more than one pair.

How to Make Period Underwear Last Longer

  1. Rinse it soon

    Rinse it in cold water soon after you take it off. Do not let a used pair sit for long. Dried blood is harder to wash out.

  2. Wash cold and gentle

    Use cold water and a gentle cycle. A mesh laundry bag can help protect it.

  3. Skip softener and bleach

    Fabric softener can coat the layers and make them soak up less. Bleach can harm the fabric.

  4. Air dry

    Hang it or lay it flat to dry, away from direct heat. Heat can wear out stretchy fabric over time.

  5. Follow the care label

    Always check the care label on your pair. It has the final say.

Why a Few Pairs Help

When you rotate a few pairs, each one gets washed less often. That means less wear on each pair. It also gives each pair time to dry fully before you wear it again.

Kischt comes in 3-packs and 5-packs. A 3-pack is $19.98 a pair, and a 5-pack is $17.99 a pair.
