Menstrual pants are a game-changer. No more worrying about shifting pads, constantly changing tampons, or that uncomfortable feeling of disposables. But how do these panties work? How do you wear them, do you need extra protection, and how long can you keep them on? In this comprehensive guide, we answer all your questions about using menstrual pants. Whether you're new to them or just curious to learn more, here’s everything you need to get started with confidence.
Step by step: Wearing menstrual panties
Putting on menstrual panties might seem mysterious if you're used to conventional menstrual products. But trust us: it's easier than you think. Here’s a simple guide to help you get started.
Preparation: Wash first
Before using your menstrual panties for the first time, we recommend washing them twice. This may seem like an extra step, but it's essential for optimal absorption. Think of a new pad: after a wash, it absorbs moisture much better. Hand-wash in cold water or machine-wash at low temperature (40°C maximum) with a mild detergent. Then, leave them to air-dry. Once this preparation is complete, your panties are ready to do their job.
Put it on, it's easy
Once your panties are washed and dry, just slip them on like any other underwear. No complicated instructions, no extra steps. Whether you’re wearing jeans, a dress, or leggings, our panties fit seamlessly into your daily outfit. They’re soft and comfortable, made from materials like bamboo or organic cotton, and they stay in place without constricting. This makes them the ideal choice for a busy day at work or a relaxing afternoon at home.
What next?
When your day is done (or earlier, depending on your flow), rinse the panties in cold water to remove blood and other residues. Then machine wash on a gentle cycle. Avoid using fabric softener or bleach – they can damage the absorbent layers. Let them air-dry, and they’ll be ready for your next cycle. It’s that simple!
With these simple steps, you’re fully equipped to wear your menstrual panties. But you might be wondering: is that really enough?
Do I need extra protection? No !
One of the great things about menstrual underwear is that you don’t need to add anything. No pads, no tampons, no panty liners – the panties do it all. How is this possible? Let’s take a closer look at the composition.
The magic of four layers
A menstrual panty has four clever layers in the crotch that work together:
1. Top layer: A soft, breathable fabric that quickly wicks away moisture and keeps you dry.
2. Absorbent layer: An ultra-absorbent core that captures menstrual flow - up to the equivalent of three tampons, depending on the model.
3. Waterproof layer: A waterproof fabric (PUL) that prevents any leakage, even on heavy days.
4. Outer layer: A comfortable fabric that gives the panty the appearance of classic underwear.
These menstrual panties are designed so you don’t have to worry about leaks, even if you’re out all day. Whether your flow is light, normal, or heavy, there’s a pair to suit. At Moi et Marie, each product description indicates the precise level of absorption, so you can choose with confidence.

No complications, just comfort
You may be thinking, "What if I want more security?" We understand. Especially at first, it takes a little time to fully trust your panties. But after a few days, you'll realize: it really works. No more juggling with wings that come off or tampons to change every hour. Just slip them on and off you go. And the icing on the cake? It's better for your body - no risk of toxic shock syndrome like with tampons, and no irritating plastic like with many pads.
In short: there's no need for extra protection. Your menstrual panties are your all-in-one solution.
How long can I wear it?
A common question: how long can you wear your menstrual panties before changing them? It depends on your flow, but we’ll provide a clear overview so you know what to expect.
Up to 12 hours of comfort
Most menstrual pants are designed to be worn for 8 to 12 hours. This means you can put them on in the morning, go to school or work, and only need to change them when you get home in the evening. Practical for a busy day, don’t you think? At Moi et Marie, all our panties are tested for safe, long-lasting absorption, so you’ll feel fresh and confident – even after hours.
- Light flow: Up to 12 hours without worries. Ideal for the end of your period or for light bleeding.
- Normal flow : 8-10 hours, depending on your day. Sufficient for a day's work or school.
- Abundant flow : 6-8 hours. On the heaviest days, you can change it a little earlier, but it holds up well.
Listen to your body
Every period is unique, so it may take a little time to find what's right for you. Heavy flow? You can change it at midday for added peace of mind. But even then, don't worry about leaks - the waterproof diaper does its job. After a few cycles, you'll know your panties by heart and know exactly when it's time to switch to a new pair.
Practical on the go
Let's say you're out all day. No problem. When you get home in the evening, rinse off the panties and put on a new pair. Travelling and can't wash right away? Put the used panties in a small airtight bag (like a reusable waterproof pouch) and wash them later. That way, you stay flexible, wherever you are.
Why it will become your favorite
Let's be honest: getting your period isn't always fun. But menstrual briefs make it a whole lot easier. No stress, no extra gear in your bag, and comfort that lasts all day. Whether this is your first period or you've been looking for a longer-lasting option, this guide shows you just how easy it can be.
