Menstrual panties made in Quebec
Discreet lining in natural fibers
An absorbent lining is already present in the menstrual brief to create a natural barrier for the underwear. Although insufficient without a menstrual insert, it helps prevent unexpected leaks. The lining serves as a soft, integrated panty liner inside the menstrual brief. It is longer at the front and back than standard sewing templates to ensure perfect protection.
La doublure 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 brief
A breathable, waterproof barrier sewn into the underwear is made of a thin layer of 100% PUL. This makes the menstrual underwear impervious to any blood leaks that might try to pass through.
Light or heavy flow for menstrual underwear?
The menstrual underwear adapts well to all flows. For more comfort, women with a heavy flow may prefer to wear a Diva Cup cup ou d menstrual cup. For light to medium flow, the period underwear with 3 inserts is sufficient for daytime use. The insert also allows you to change only the absorbent part 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:
-
A 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 using snap fasteners (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 help make a meaningful eco-responsible gesture for the environment. 💚
