Menstrual panties made in Quebec
Discreet lining in natural fibers
An absorbent lining is already present in the period 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 period underwear. It is longer at the front and back than standard sewing templates to ensure perfect protection.
The lining is offered in two colors. Natural (color natural unbleached): for sensitive skin or skin prone to infections that allows the menstrual flow to be seen. Black: For easier maintenance since persistent stains are not visible.
Breathable and waterproof barrier on the inside of the period 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 that would try to pass through it.
Light or heavy flow for a period panty?
The menstrual underwear adapts well to all flows. For greater comfort, women with a heavy flow might prefer to wear a Diva Cup cup or of a menstrual discFor light to medium flow, the period underwear with 3 inserts is sufficient for daytime use. The insert also allows you to change only the inner pad without having to change the underwear during the day.
Removable menstrual insert
It is possible to add a removable pad to the underwear to easily adapt to the menstrual cycle:
-
One insert by day or by night Marie thread (optional) :
- Ensures 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 securely in place no matter the activity.
- Interchangeable as many times as you want throughout your menstrual flow.

Hemp is the future for the environment. Its processing requires

• Maximum absorbency
• Soft when blended with cotton
