Menstrual underwear made in Quebec
Discreet lining in natural fibers
A moisture-wicking liner is already present in the menstrual underwear to create a natural barrier for the panties. 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 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, 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 period underwear?
The menstrual underwear adapts well to all flows. For added comfort, women with a heavy flow might prefer wearing a Diva Cup stem or of 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 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 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.
- Attaches with snap fasteners (ultra-thin, you won't even feel them, 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 at ease in your own skin, whether you have your period or not. And together, now more than ever, we’re helping make an important eco-responsible gesture 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 limit odors
• Hypoallergenic to eliminate irritation
• Maximum absorbency
• Soft when blended with cotton
Choose the right size for washable menstrual underwear:
Acheting menstrual panties online can be complicated. Every woman deserves a proper fit and to be comfortable during her period. Here are some tips regarding the Marie fil size chart.
Marie menstrual underwear size chart
Order the right 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 sore belly.
