Depending on your profile, habits, and the nature and intensity of your flow, you can choose a specific type of menstrual underwear. It's important to carefully review the features as well as user reviews before making your choice.

The heavy or very heavy flow period underwear is an essential part of your period routine. This style is specially designed to handle heavy or very heavy flows and is especially practical for many women.

With its high absorbency, the very heavy flow period underwear provides strong, reliable protection for hours. No wetness, no leaks, no saturation, and no bad odors; the heavy flow period underwear can easily manage periods with a copper IUD, for example. These styles also work well for postpartum bleeding. Its absorbent layer runs from the front to the back of the underwear and goes up to the back for wide, flawless coverage.

Main feature: an impressive absorbency, equivalent to 5 tampons.

No toxic shock syndrome, no irritation, no dryness, no risk to your health, your intimacy, or your feminine balance—the menstrual panty is an external hygienic protection that’s reusable, washable, and made with transparent, healthy ingredients.
We’re all for organic menstrual panties and local manufacturing, whether French or European. Many brands are making a real effort to offer high-quality panties made with healthy materials like organic cotton or organic bamboo. Pay attention to different labels and certifications (OEKO-TEX) to make sure your panties are top quality!

Main feature: the brand should clearly highlight the composition, as well as any labels, certifications, patents, or other results proving the fabrics used are safe.

Period underwear that’s absorbent, reliable, and super discreet? Invisible, seamless period panties are favorites among athletes. With these ultra-discreet styles, you don’t have to give up your favorite workout leggings. The fabrics are often very thin and soft, and the seams are either flat or invisible.

We especially love the second-skin feel and the softness of the fabric.

Main feature: seamless and invisible is great, but never forget that high absorbency is key if you're working out intensely.

Period underwear can be very useful and practical if you have irregular periods. Unexpected or irregular periods can come earlier or later than expected. These surprise periods are always inconvenient, especially when you’re away from home.

Period underwear can easily fit in your purse. That makes it a practical and comfortable emergency backup you can always rely on.

Main feature: For irregular periods, why not try a style of underwear with an easy-to-remove or slip-on fastening system?

Light flow, spotting, vaginal discharge—period underwear is super practical for managing these types of leaks. To avoid using traditional disposable pantyliners, light-flow period underwear is ideal. Period thongs or even period strings can absorb light menstrual flow, spotting (light, intermittent bleeding), and vaginal discharge throughout your cycle.

Main feature: since you’ll wear these all day, choose protection that’s comfortable and lined with organic cotton.
