Are you wearing period panties and wondering how it's possible to feel dry while bleeding? Or maybe you're hesitant to buy some, but want to understand how these period panties work to give you peace of mind? In this article, we'll explain how these little gems of technology work! Let's get started on understanding how period panties work .
How do menstrual panties work?
Are you looking for a new sanitary protection and would like to know more about period panties, particularly how they work? At first glance, you wouldn't guess it, but period panties are true technological feats. Designed to absorb our menstrual flow, they incorporate technology that provides comfort and protection. They are made up of three distinct layers : let's explore them together.
1. A draining layer material to feel dry
The first layer is made from a highly draining material . This material aims to quickly absorb menstrual flow , thus ensuring a persistent feeling of dryness. It acts as an instant barrier between moisture and the skin, allowing you to stay dry and comfortable throughout the day.
💡Our advice: Choose panties that are OEKO-TEX® STANDARD 100 certified. This certification guarantees that the panties do not contain any chemicals that are harmful to your body and the environment. Especially if you are prone to allergies and irritations caused by sanitary napkins !
2. An absorbent and antibacterial material to capture blood and neutralize odors
The second layer is made from a material that is both absorbent and antibacterial . It is specifically designed to capture blood effectively while neutralizing odors. Thanks to its antibacterial properties, it also prevents the proliferation of bacteria, ensuring optimal hygiene throughout the day.
3. A waterproof (and breathable) material to prevent leaks
The third layer is made from a waterproof yet breathable material. This combination ensures maximum protection against leaks while allowing the skin to breathe. Not only does it guarantee optimal safety, but it also offers unparalleled comfort for a feeling of freshness all day long.
Period panties are suitable for different flows
Just as period products such as sanitary napkins or tampons are available in different styles adapted to different flows, menstrual panties also offer this variety. Their function, depending on the flow, is therefore the same:
Light flow
For lighter flow days, some menstrual panties are specifically designed with a lower absorbency, adapted to this level of bleeding. For this type of flow, we generally find thongs, for example. Despite their lower absorbency compared to models for heavier flows, these panties offer effective and reliable protection for days of light bleeding.
Average flow
During average flow days, specially designed menstrual panties are available to manage this amount of bleeding. Although they have higher absorbency and are generally slightly thicker than light flow models, they maintain a high level of comfort. These panties have a similar appearance to traditional panties.
Heavy flow
Finally, with significantly higher absorbency, these briefs are designed to provide continuous protection for many hours without worrying about leaks. While they're thicker to meet this requirement, they're made to ensure optimal comfort.
And to your activities
In this section, although the technology of menstrual panties remains unchanged , the innovation lies in their integration into clothing such as your swimsuits or leggings. Let's take a look at the different models suitable for these activities.
For sport
Sports require freedom of movement and optimal comfort, even during your period. To meet these specific needs, there are now menstrual panties specially designed for sports . These protections come in different shapes to adapt to each discipline.
Menstrual leggings are perfect for activities like yoga, running, or the gym. Incorporating menstrual panties, they offer a dual function: that of traditional sports leggings combined with menstrual protection, without visible seams or discomfort.
For cycling enthusiasts or those who enjoy activities requiring more ventilation, menstrual cycling shorts are the ideal solution. These shorts, equipped with built-in menstrual panties, guarantee optimal protection while allowing for better ventilation, which is essential during intense exercise.
These innovations therefore allow every woman to continue practicing her favorite sporting activity with complete peace of mind, without having to worry about leaks or the inconveniences associated with menstruation.
For the bath
Swimming during your period can be a challenge for many women, but thanks to technological advances, it's now possible to swim with peace of mind. Menstrual panties suitable for swimming were designed to address this specific concern.
Thanks to their leak-proof technology and an absorbency equivalent to 2 tampons, these panties guarantee an optimal seal. This means you can be assured of zero blood dispersion in the water, zero bulging once the panties are wet, and zero risk of staining your pad.
Plus, these menstrual panties are made from materials specially designed to withstand salt and chlorinated water . And because extra protection is never too much, they also protect against UV rays with a UPF 50+ rating.
Whether it's a one-piece swimsuit or a simple swim brief , these innovations ensure that menstrual days will never again be a hassle during your trips to the beach or pool.
