Floral Harmony Menstrual Brief
The Marie FIL menstrual panties look like a regular pair of 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!
Culotte menstruelle made in Quebec
Discrete 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 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 (color naturelle non blanchie): for sensitive skin or skin prone to infections, which allows you to see 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 inside the panty 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 menstrual panties?
La culotte menstruelle s'adapte bien à tous les flux. Pour plus de confort, les femmes avec un flux abondant pourraient préférer le port d'une Diva Cup cutter or of a menstrual disc. For a light to medium flow, the menstrual brief 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.
Insert removable menstrual
It is possible to add a removable insert to the panties 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.
- Snapped on using press studs (ultra-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 period underwear means choosing to be comfortable and feel good in your skin, whether you have your period or not. And together, more than ever, we’re helping make an important eco-friendly 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 reduce odors
• Hypoallergenic to eliminate irritation
• Maximum absorption
• Soft when blended with cotton
Choose the right size of washable period underwear:
Buying menstrual underwear 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 sizing chart.
Size chart for Marie menstrual underwear
Order the right size of period 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.
