Soft Comfort. Serious Protection.

Heavy-flow period underwear can still feel breathable, flattering and easy to wear.

The EvaBody Heavy Flow Bamboo Bikini combines naturally soft bamboo-rich fabric with a smooth, classic bikini fit, giving you dependable protection without the bulky feel of traditional period underwear. Gentle against sensitive intimate areas, the flexible fabric moves comfortably with your body and sits discreetly beneath clothing.

Designed for heavier-flow days and overnight wear, it offers reliable absorbency to help you feel dry, secure and confident for longer. The bikini silhouette provides comfortable coverage through the front and back without the fuller feel of a high brief, making it a versatile choice for both daytime wear and sleep.

It can also be worn for light bladder leaks, discharge or whenever you need added reassurance.

  2. Machine wash with similar colours on a cold or gentle cycle at a maximum of 30°C using mild detergent.
  3. Do not use bleach or fabric softener.
  4. Air dry completely in a well-ventilated area. Do not tumble dry.
