Cyan Menstrual Briefs

The Marie Fil menstrual underwear looks like a regular pair of women's briefs, except it is perfectly adapted for periods. Indeed, this feminine menstrual protection allows women to lead an active life every week of the month... And all that while being an eco-responsible alternative!

Menstrual panties made in Quebec

Discreet lining in natural fibers

An absorbent lining is already present in the menstrual underwear to create a natural barrier within the brief. Although 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 natural unbleached): for sensitive skin or prone to infections which allows the menstrual flow to be seen. Black: For easier maintenance since persistent stains are not visible.

Breathable, waterproof barrier inside the period underwear

A breathable, waterproof barrier sewn into the underwear is made from a thin layer of 100% PUL. This makes the menstrual underwear invincible against any blood leaks that might try to penetrate it.

Light or heavy flow for menstrual underwear?

The menstrual underwear adapts well to all flow levels. For added comfort, women with a heavy flow may prefer to wear a Diva Cup cup or of a menstrual cup. For light to medium flow, the menstrual briefs with 3 inserts are sufficient for daytime use. The insert also allows you to change only the inside without having to change the underwear during the day.

Removable menstrual insert

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.
  • Fastens using snap buttons (super 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.

Porting 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 an important eco-responsible gesture for the environment. 💚

Marie menstrual underwear size chart

Order the right size of menstrual underwear by measuring your hips, above the buttocks, using a measuring tape held parallel to the floor. If you’re between two sizes, choose the larger one. Periods often come with bloating or a sore stomach.
