Classic Comfort. Serious Protection.

Heavy-flow protection can feel soft, secure and easy to wear every day.

The EvaBody Heavy Flow Classic Cotton Boyshort combines a soft cotton-rich body with a supportive, full-coverage silhouette through the hips, back and upper thighs. Its clean, sporty design offers a comfortable, stay-put fit that moves with you and feels more like your favourite everyday underwear than a traditional period product.

Designed for heavier-flow days and overnight wear, it provides dependable absorbency to help you feel dry, comfortable and confident for longer. The boyshort cut offers added coverage and reassurance, making it a practical choice for busy days, sleep or whenever you want a little more support.

It can also be worn for light bladder leaks, discharge or added backup protection. Available in black and grey, it is an easy, versatile staple for your period underwear rotation.

Soft cotton comfort. Secure coverage. Protection you can rely on.
