High-Waist Menstrual Panties Winter Roses
The Marie Fil menstrual briefs look like a pair of regular women's underwear, except they are perfectly adapted for periods. Indeed, this feminine menstrual protection allows women to lead an active life every week of the month... And all while being an eco-responsible alternative!
Menstrual briefs made in Quebec
Discreet lining in natural fibers
A 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 surprises. The lining 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 (unbleached natural shade): for sensitive or infection-prone skin that allows you to see menstrual flow. Black: For easier maintenance since persistent stains are not visible.
Breathable and waterproof barrier inside the menstrual underwear
A breathable, waterproof barrier sewn into the underwear is made from 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 menstrual underwear?
The menstrual underwear adapts well to all flows. For added comfort, women with a heavy flow may prefer wearing a Diva Cup cutter or of a menstrual cup. For a light to medium flow, the menstrual underwear alone is sufficient for daytime use. An 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:
-
Un insert day or night Marie thread (optional) :
- Ensures a double absorbent and waterproof protection thanks to its composition identical to the gusset of the menstrual underwear.
- Snaps onultra-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.
Wearing the Marie fil menstrual underwear means choosing comfort and feeling good in your skin, whether you have your period or not. And together, more than ever, we’re helping make an important eco-responsible contribution to 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
Choosing the right size of washable menstrual underwear:
Buying 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.
Size chart for Marie fil menstrual panties
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.
