Organic Spruce Menstrual Panties
The Marie fil period underwear looks like a regular pair of women’s panties, except it’s perfectly suited for menstruation. In fact, this feminine menstrual protection allows women to lead an active life every week of the month... all while being an eco-responsible alternative!
Period 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 insufficient without a menstrual insert, it helps prevent surprises. The lining acts as a soft protector built into the inside of the period 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 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 inside 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 brief?
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 menstrual cup ou d'un menstrual disc. For a light to medium flow, the menstrual brief with 3 inserts is sufficient for daytime. The insert also lets you change only the inner pad without having to change the whole 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) :
- Ensures a double absorbent and waterproof protection thanks to its composition identical to the gusset of the menstrual brief.
- Snaps on using press studs (hyper 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 feel comfortable and confident in your own skin, whether you’re on your period or not. And together, more than ever, we’re making an important eco-friendly 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 absorption
• Soft when blended with cotton
