How long can you wear your menstrual panties?

Menstrual panties are the most sustainable alternative to take care of your intimate hygiene, but what we don’t know is how long we can use them. Today, on the FreeU blog we give you all the information you need to take care of your period safely.

There are many advantages to menstrual panties as a means of protection and hygiene against menstruation. On the one hand, they are reusable and can withstand numerous washes, which helps to protect the environment. This type of menstrual panty is very practical, as you have both underwear and protection in a single garment. In addition, compared to traditional sanitary towels, menstrual panties do not move or shift, which makes them perfect for avoiding chafing and irritation, which is helped by the fact that they are made from natural fabrics such as bamboo cotton.


Over the course of a day, menstrual panties can be worn for between 4 and 8 hours. This depends on your menstrual flow and the regulation of the panty itself. They are very absorbent and you will find three different strengths, just like with a tampon.

Reusable menstrual panties reduce odour considerably, but also leakage and therefore the worry about staining or the mental burden of having to change pads disappears.


How many menstrual pads should I have?

Again, this depends on whether you have a light, medium or heavy flow. However, it is advisable to have at least 5-7 pairs of menstrual panties, so that you can rotate them during a menstrual cycle. They are also perfect to replace the panty liners at the end of the cycle.


How long can they be worn?

The three-layer FreeU menstrual panties can be worn for 12 hours continuously. In principle, you can wear them all day or all night without needing to change them, although this will also depend on the amount of flow you have and the day of your cycle, so you may want to combine them with another method for the first few days, although it’s not strictly necessary, it can help you feel more confident while you get used to the change.

How long do they last?

We already know the FreeU advantages.  One of them is the lifespan of this type of protection. In fact, a menstrual panty can be used for up to 2 years or more depending on how you use them.

This also depends on the material the panties are made of and how often they are washed. However, even if panties wear out over time, like all types of clothing, their absorbency is not lost. Finally, the use of reusable menstrual panties significantly reduces the cost of disposable sanitary protection, minimises the impact of litter to seas and rivers and contains no microplastics.


Free yourself from pads and tampons and live your menstruation in a cleaner and more natural way with you and the environment.
