Mustard Menstrual Briefs

The Marie menstrual underwear looks like a regular pair of women's panties, 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 it does so while being an eco-responsible alternative!

Menstrual underwear made in Quebec

Discrete lining in natural fibers

An absorbent lining is already present in the menstrual briefs to create a natural barrier for the underwear. Although insufficient without a menstrual insert, it helps prevent surprises. The lining acts as a soft, built-in panty liner inside the menstrual briefs. 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 you to see menstrual flow. Black: For easier maintenance since persistent stains are not visible.

Breathable, waterproof barrier on the inside of 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 trying to pass through.

Light or heavy flow for period panties?

The menstrual underwear adapts well to all flow levels. For greater comfort, women with a heavy flow may prefer to wear a Diva Cup menstrual cup ou d menstrual disc. For light to medium flow, the menstrual panties with 3 inserts are sufficient for daytime. 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 panties to easily adapt to your menstrual cycle:

• One insert by day or by night Marie thread (optional) :
  • Ensures 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 menstrual briefs 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. 💚

Size chart for Marie Fil menstrual briefs

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