Menstrual underwear made in Quebec
Discrete lining in natural fibers
An absorbent liner is already present in the menstrual underwear to create a natural barrier for the panty. Although not sufficient without a menstrual insert, it helps prevent unexpected leaks. The liner acts as a soft, built-in panty liner inside the menstrual 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 (colour unbleached natural): for sensitive or infection-prone skin that allows menstrual flow to be visible. Black: For easier maintenance since persistent stains are not visible.
Breathable, waterproof barrier inside the menstrual panties
A breathable, waterproof barrier sewn into the inner lining of the underwear is made from a thin layer of 100% PUL. This makes the menstrual underwear impervious to any blood leaks that might try to pass through it.
Light or heavy flow for period panties?
The menstrual underwear adapts well to all flows. For added comfort, women with a heavy flow might prefer wearing a Diva Cup cup ou d'un menstrual discPour light to medium flow, the menstrual panties with 3 inserts is sufficient for daytime. Liners also allow you to change only the interior 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:
-
A 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 on (hyper 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.

Why choose hemp?*
Hemp is the future for the environment. Its processing requires
very little water and no chemicals. That's why Marie prefers hemp to bamboo. This fabric also has several properties:
• Antibacterial to limit odors
• Hypoallergenic to eliminate irritation
• Maximum absorption
• Soft when mixed with cotton
