Fir Regular Menstrual Panties

The Marie Fil menstrual panties look like a regular pair of women's underwear, 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!

Menstrual panties 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. While insufficient without a menstrual insert, it helps prevent surprises. 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 available 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 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 impervious 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 might prefer wearing a Diva Cup or of a menstrual disc. 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 inner layer 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:

• A insert by day or 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 (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 comfort and feeling good in your skin, whether you have your period or not. And together, now more than ever, we’re helping make an important eco-responsible gesture for the environment. 💚
