How EvaBody Period Underwear Works

Four layers. One smart protection system.

EvaBody period underwear combines the look and feel of underwear you actually want to wear with built-in absorbency and leakproof protection.

Each of its four specialised layers performs a different role, from drawing moisture away from your skin to absorbing fluid and helping prevent leaks, so you can move through your day with greater comfort and confidence.

What happens when you wear it?

Period fluid passes through the moisture-wicking top layer and into the absorbent core, where it is captured and securely held.

A leak-resistant barrier provides an additional layer of protection to help prevent fluid from reaching your clothing. The soft outer fabric completes the design, giving EvaBody the comfortable look and feel of everyday underwear.

Inside EvaBodyā€™s four-layer technology

1. Moisture-wicking top layer

The layer closest to your body is designed to draw moisture away from your skin and direct it towards the absorbent core, helping you feel drier and more comfortable.

2. Absorbent core

The absorbent core captures and securely holds period fluid. Its capacity varies between light, moderate, heavy and super-absorbency styles, allowing you to choose protection suited to your flow.

3. Leak-resistant barrier

This protective layer helps prevent absorbed fluid from passing through to your clothes, providing added reassurance while you work, sleep, exercise or go about your day.

4. Soft outer fabric

The final layer creates the smooth exterior of the underwear. It is designed to feel soft and comfortable while giving each pair the appearance of stylish everyday underwear.

Protection matched to your flow

The same four-layer system is used across EvaBodyā€™s different absorbency categories, while the capacity and protective coverage vary depending on the product.

  • Light Flow: for spotting, lighter days or backup protection
  • Moderate Flow: for regular-flow days and dependable everyday protection
  • Heavy Flow: for heavier days or when you want stronger coverage
  • Super Absorbency: our highest-capacity protection for very heavy-flow days or extended wear

Everyoneā€™s flow is different, so your ideal wear time will depend on your body, cycle and chosen absorbency.

Using EvaBody period underwear is simple:

  1. Choose a style and absorbency suited to your flow.
  2. Wear it on its own, just like regular underwear.
  3. Change into a fresh pair when needed, before the absorbent core reaches capacity.
  4. Rinse in cold water, machine wash gently and air dry completely.
  5. Wear it again during your next cycle.
