Fraisinette Menstrual Brief
The Marie floppy menstrual panties look like a pair of regular women's briefs, 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 period underwear to create a natural barrier for the panties. Although insufficient without a menstrual insert, it helps prevent unexpected leaks. The lining acts as a soft, built-in panty liner inside 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 care as persistent stains are not visible.
Breathable, waterproof barrier inside the menstrual underwear
A breathable, waterproof barrier sewn into the inside of the underwear is made of a thin layer of 100% PUL. This makes the menstrual underwear invincible to any blood leaks that would try to pass through it.
Light or heavy flow for a menstrual brief?
The menstrual underwear adapts well to all flows. For more comfort, women with a heavy flow might prefer wearing a Diva Cup ou d'un menstrual disc. For a light to medium flow, the menstrual briefs with 3 inserts are sufficient for daytime use. The insert also allows you to change only the interior 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 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.
- 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 menstrual underwear means choosing to be comfortable and feel good in your own skin, whether menstruating or not. And together, 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. It'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 mixed with cotton
