Period Panties Pine grove
The Marie period panties look like a regular pair of women's underwear, except they are perfectly adapted for menstruation. Indeed, this feminine menstrual protection allows women to lead an active life every week of the month... All while being an eco-responsible alternative!
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 unexpected leaks. The lining serves as a soft panty-liner integrated into 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 (color natural unbleached): for sensitive skin or skin prone to infections that allows visibility of menstrual flow. Black: For easier maintenance since persistent stains are not visible.
Breathable, waterproof barrier inside 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 might try to pass through.
Light or heavy flow for period panties?
The menstrual brief adapts well to all flows. For greater comfort, women with a heavy flow may prefer wearing a Diva Cup cup or of menstrual disc. For a light to medium flow, the menstrual brief with 3 inserts is sufficient for daytime use. The insert also lets you 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:
-
One insert day or night Marie thread (optional) :
- Ensure a double absorbent and waterproof protection thanks to its composition identical to the gusset of the menstrual underwear.
- Fastens with snap buttons (ultra-thin, you won't feel them, we promise!), to stay securely in place no matter the activity.
- Interchangeable as many times as you want throughout your menstrual flow.
Wearing the Marie Fil period underwear means choosing to be comfortable and confident in your skin, whether you have your period or not. And together, more than ever, we help make an important eco-responsible choice for the environment. 💚

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 reduce odors
• Hypoallergenic to eliminate irritation
• Maximum absorbency
• Soft when blended with cotton
