Underwear designed for period days is perfect for those looking to ditch plastic from their lives, but how do they actually work?

The battle against plastic has been going on for some time in the field of intimate hygiene, in which the menstrual cup seems to be, to date, the preferred option. However, It is still hard to find many period alternatives that can be considered really sustainable, while those that are, like the menstrual cup, do not always turn out to be the most comfortable or convenient.

But the good news is that brands are more conscious of climate change and are creating sustainable options that are good for us and the planet, so, for the time being, it seems like period underwear has become the most efficient choice.

How Does Period Underwear Work?

Although they look like regular underpants, the difference lies in the special fabric with which they are made, which allows the absorption of menstrual flow without transferring to your beautiful clothes. The fabrics are also antibacterial to prevent odours and water-impermeable so you can forget about any uncomfortable feelings or potential leaks. The key with period underwear is that it can be washed normally after each use, so they are reusable and, therefore, environmentally friendly compared to single-use products such as tampons.

What About Possible Leaks Or Transfers To Clothes?

The biggest concern when trying them is, obviously, that they really prevent possible leaks or transfer stains to clothes. Although they can be used together with other intimate products such as tampons or menstrual cups, these panties have sufficient absorption capacity to wear them without any problem or accident.

How Long Can I Wear Period Panties? 

Normally, they can be used all day or all night without changing them, but you need to keep in mind that it depends on the amount of flow you have and the day of the cycle you are in. In fact, some women prefer to use them together with other hygiene products to feel more secure. -They can absorb between 15 and 20 ml, which is almost what a woman loses on average during the entire duration of her period-.
