Menstrual underwear made in Quebec

Discreet 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 surprises. The lining acts as a soft panty liner integrated into the menstrual underwear. It is longer at the front and back than standard sewing patterns to ensure perfect protection.

The lining is offered in two colors. Natural (color unbleached natural): for sensitive skin or skin prone to infections 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

A breathable, waterproof barrier sewn into the underwear is made of a thin layer of 100% PUL. This makes the menstrual underwear invincible to any blood leaks trying to pass through it.

Light or heavy flow for a menstrual underwear?

The menstrual panties adapt well to all flows. For greater comfort, women with a heavy flow might prefer wearing a Diva Cup cup or of a menstrual disc. For light to medium flow, the menstrual underwear with 3 inserts is sufficient for daytime. The insert also allows you to change only the inner layer without having to change the underwear during the day.

Insert removable menstrual

It is possible to add a removable insert to the underwear to easily adapt to the menstrual cycle:

• One insert by day or by night Marie thread (optional) :
  • Ensure a double absorbent and waterproof protection thanks to its composition identical to the gusset of the menstrual underwear.
  • Snaps onhyper thin, you won't feel them, promise!), to stay firmly in place no matter the activity.
  • Interchangeable as many times as you want throughout your menstrual flow.
