Discrete lining in natural fibers
An absorbent lining is already present in the menstrual underwear to create a natural barrier for the panties. Although insufficient without a menstrual insert, it helps prevent unexpected leaks. The lining acts as a soft protector integrated into the inside of the menstrual underwear. It is longer at the front and back than standard sewing patterns to ensure perfect protection.
The lining is available in two colors. Natural (color natural unbleached): for sensitive or infection-prone skin that allows you to see menstrual flow. Black: For easier maintenance since persistent stains are not visible.
Breathable and waterproof barrier inside the menstrual underwear
Une breathable, waterproof barrier sewn into the interior of the underwear is made of a thin layer of 100% PUL. This makes the menstrual underwear invincible against any blood leaks that would try to pass through it.
Light or heavy flow for menstrual underwear?
The menstrual underwear is suitable for all flows. For greater comfort, women with a heavy flow may prefer to wear a Diva Cup menstrual cup ou d'un menstrual discFor light to medium flow, the menstrual underwear with 3 inserts is sufficient for daytime use. The insert also allows you to change only the inner layer without having to change the underwear during the day.
