What Are Period Panties? Your Guide to Menstrual Underwear

Period panties, also known as menstrual underwear, are revolutionizing menstrual care. They provide reliable protection without the risks associated with tampons or menstrual cups, like toxic shock syndrome (TSS), while offering unmatched convenience and sustainability.

Definition of Period Panties

A period panty is specialized underwear worn during menstruation. It combines the comfort of regular lingerie with a highly absorbent core that serves as effective period protection. Typically 3mm thicker than standard underwear, it can hold the equivalent of three tampons and be worn for up to 12 hours.

Period panties feature three key layers:

  • A soft cotton layer against the skin;
  • A super-absorbent plant-based fabric, such as in Herloop period panties;
  • A waterproof layer to prevent leaks and stains.

Who Can Use Period Panties?

Every woman can benefit from period panties, regardless of flow intensity, age, or style preferences. A wide variety of washable options ensures the perfect fit for your needs.

Choose based on your flow:

  • Light flow
  • Medium flow
  • Heavy flow

How to Use Period Panties

Use them as standalone protection or pair with a liner for extra security. For seamless cycle management, keep at least three or four pairs on rotation. They're comfortable for day and night wear.

Is There a Risk of Leakage?

Most period panties last up to 12 hours without issues, though this varies by flow. Consult the brand for the best model tailored to you.

What About Odors?

Odor concerns are common, but the absorbent core uses natural antibacterial fibers like bamboo or eucalyptus, neutralizing smells for up to 12 hours. Always wash and air-dry thoroughly to maintain this property.

Benefits of Period Panties

Here are the key advantages:

  1. Superior absorbency: Holds the equivalent of 2-5 tampons, depending on flow and model;
  2. All-day comfort: Soft and non-restrictive during sensitive times;
  3. Everyday practicality: Easy to change anywhere—no sink required like with cups;
  4. Clean composition: Free from chemicals and nanoparticles for natural protection;
  5. Eco-friendly impact: Reusable for about 3 years, avoiding the 11,000 disposable pads used in a lifetime.

Any Downsides?

While excellent, consider these:

  • Minimal leak risk with very heavy flows;
  • Not ideal for swimming, though menstrual swimsuits are emerging;
  • Slightly thicker, potentially visible under tight clothes;
  • Carry spares for changes.

How Much Do Period Panties Cost?

The average price is €35 per pair. They pay for themselves quickly by replacing disposables for around 3 years.

Tips for Caring for Your Period Panties

To extend their life for years:

  1. Soak in cold water;
  2. Rinse until water runs clear;
  3. Wash with stain-removing soap (no glycerin) or in a delicate machine cycle inside a lingerie bag.
