What technological advances are behind menstrual panties?

The technological advances behind menstrual panties have been significant in recent years, leading to improvements in their effectiveness, comfort and sustainability. Some of the major technological advances include:

  • High-tech materials: New materials have been developed for absorbent layers, such as terry bamboo, which is a mixture of bamboo, cotton and polyester. These materials offer greater absorption and retention capacity for menstrual flow, keeping moisture away from the skin and preventing leaks. Take a look at our Full CoverType and you will realize all the benefits it offers you .
  • Breathable fabrics: Technological advances in fabrics have allowed the creation of menstrual panties with breathable layers that provide better air circulation and greater comfort during use.
  • Water-repellent layers: Waterproof laminated polyurethane (PUL) layers have been developed that act as barriers to prevent leaks and keep outerwear dry.
  • Ergonomic design: These menstrual panties fit comfortably to the body, providing greater comfort and better support during movement.
  • Invisible seam system: Advanced sewing techniques have been implemented to reduce the presence of seams and achieve greater softness and comfort in the fit.
  • Chemical-free printing and dyeing: Some brands have adopted printing and dyeing techniques without the use of harmful chemicals, making them safer for the skin and the environment.
  • Computer modeling and testing: Computer modeling and testing has allowed manufacturers to improve the shape and fit of menstrual panties, ensuring that they fit correctly to the anatomy of the female body.
  • Usability and comfort studies: Studies and tests have been carried out to evaluate the usability and comfort of menstrual panties, which has led to their design and performance being optimized.
  • Sustainable production technology: Luna Roja has implemented more sustainable production technologies, such as the use of renewable energy and the reduction of waste in the manufacturing process.

How do menstrual panties prevent moisture?

Menstrual panties prevent humidity thanks to their design and the materials with which they are made. These underwear are made up of several layers that work together to keep you feeling dry during your menstrual period.

  • Skin contact layer: The layer that is in direct contact with the skin is made of soft and breathable materials, such as cotton, bamboo or other technological fabrics. These materials allow moisture to move away from the skin, providing a feeling of freshness and comfort.
  • Absorbent layer: In the center of the menstrual panties, there is an absorbent layer that retains menstrual flow. This layer is usually made of an absorbent material, such as terry bamboo (a mixture of bamboo, cotton and polyester), which has the ability to absorb and retain liquid, keeping it away from the surface and preventing the feeling of humidity.
  • Waterproof layer: In the crotch of menstrual panties, a waterproof layer is placed, usually made of laminated polyurethane (PUL). This layer acts as a barrier that prevents leaks, preventing menstrual flow from passing through the garment and keeping outer clothing dry and protected.
  • Lining layer: Some menstrual panties also have a lining layer on the outside, which helps keep menstrual flow in place and prevents it from moving to the sides, ensuring greater protection and preventing leaks.

How much flow can menstrual panties hold?


The amount of menstrual flow that menstrual panties can retain varies depending on the model and brand, as there are different sizes and levels of absorption available on the market.

With our products you will find that the panties have an absorption capacity that ranges between 5 to 50 ml of menstrual flow.

Models designed for lighter flows usually have an absorption capacity of around 20 ml, while those intended for heavier flows can retain up to 50 ml of menstrual fluid.

Luna Roja offers different levels of absorption in its products , allowing women to choose the option that best suits their needs and specific menstrual flow.

It is important to follow the instructions to determine the absorption capacity of each menstrual panty and avoid exceeding its recommended limit.

Changing panties at regular intervals throughout the day is crucial to maintaining the comfort and effectiveness of the product throughout the menstrual period.

Additionally, considering the length and flow of your period will help you choose a menstrual panty that meets your individual needs and provides adequate protection during those days of the month.

So, is it true that they neutralize bad odor?

Menstrual panties neutralize the bad smell of menstruation thanks to the combination of materials and technologies used in their design.

Although menstrual odor is natural and not necessarily unpleasant, some women may feel discomfort from this characteristic during their period.

To address this concern, menstrual panties employ different approaches to minimize or eliminate odor:

Coating layer with antibacterial properties

Some menstrual panties are made with a lining layer that contains materials with natural antibacterial and antifungal properties, such as bamboo and silver. These materials help inhibit the growth of bacteria and microorganisms that can contribute to bad odor.

Breathability and ventilation

Breathable materials and well-ventilated layers allow air to circulate freely, helping to reduce moisture buildup and the growth of bacteria that can cause unpleasant odors.

Humidity control

Menstrual panties are designed to keep moisture away from the skin and retain menstrual flow in their absorbent layers. By keeping humidity under control, the environment conducive to the development of unpleasant odors is prevented from establishing.

Natural materials without artificial fragrances

Many brands of menstrual panties avoid using artificial fragrances or chemicals that can mask menstrual odor. Instead, they use natural materials that do not interfere with the natural aroma of menstrual flow.

It is important to note that menstrual odor is a normal characteristic and does not necessarily indicate a health problem.

However, if you have concerns about odor or any other aspect of your period, it is always advisable to consult a healthcare professional for a proper evaluation.

Recommendations to care for your menstrual panties

Taking proper care of your menstrual panties is essential to maintain their effectiveness, comfort and durability over time. Enter here and learn the 7 steps to wash and keep your period underwear in good condition .

Here are five important recommendations to take care of your menstrual panties:

Hand or machine wash in cold water: Hand or machine wash the panties in cold water to avoid using hot water as it could damage the absorbent material and waterproof layer.

If you use a washing machine, put your pantie in a mesh or protective bag to prevent it from getting caught on other clothes.

Use a neutral soap: To wash your menstrual panties, use neutral soap and avoid using harsh fabric softeners or fabric softeners or detergents.

Harsh chemicals can damage the material and reduce the absorbency of the underwear.

Drying: After washing, air dry. You should avoid the dryer, as the heat can damage the material and affect performance.

Therefore, we recommend that you hang the menstrual panties in a cool and ventilated place to ensure that they are completely dry before next use.

Do not use the iron: Avoid using the iron and do not let it dry at high temperatures to dry it. Always make sure it is completely dry before storing it to avoid mold or odors.

By following these recommendations, you will be able to prolong the useful life of your menstrual panties and keep them in optimal conditions for use.
