Menstrual underwear 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 inadequate without a menstrual insert, it helps prevent unexpected leaks. The lining acts as a soft panty liner integrated into the inside of the period 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 natural, unbleached): for sensitive skin or skin prone to infections that allows visibility of menstrual flow. Black: For easier care 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 that might try to pass through it.
Light or heavy flow for a menstrual panty?
The period underwear adapts well to all flow levels. For greater comfort, women with a heavy flow might prefer wearing a Diva cup ou d'un menstrual cup. For 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.
Removable menstrual insert
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 securely in place no matter the activity.
- Interchangeable as often 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 blended with cotton

Size chart for Marie fil menstrual panties
Order the correct size of menstrual underwear by measuring your hips, above the buttocks, using a tape measure held parallel to the floor. If you’re between two sizes, choose the larger one. Periods often come with a bloated or painful belly.
