Menstrual underwear 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. While insufficient without a menstrual insert, it helps prevent mishaps. 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 patterns to ensure perfect protection.
The lining is offered in two colors. Natural (color unbleached natural): for sensitive skin or prone to infections 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 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 underwear?
The menstrual underwear adapts well to all flows. For more comfort, women with a heavy flow may prefer wearing a Diva Cup menstrual cup ou d menstrual cupFor light to medium flow, the menstrual underwear with 3 inserts is sufficient for daytime. The insert also allows you to change only the inner pad without having to change the entire 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) :
- Provides a double absorbent and waterproof protection thanks to its composition identical to the gusset of the menstrual underwear.
- Attaches using snap fasteners (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 comfort and feeling good in your skin, whether menstruating or not. And together, now more than ever, we're helping make an important eco-responsible gesture for the environment. 💚
