Instead, we focus on safe, non-toxic materials and rigorous testing to ensure quality and safety.

More about period underwear
What is period underwear?
Period underwear is a smart solution designed to provide you with security and comfort during your period. The underwear consist of multiple layers of highly absorbent materials that effectively soak up menstrual blood, keeping you dry and comfortable.
They are developed as a sustainable alternative to traditional disposable products like tampons and pads. With proper care, period underwear can be reused for years. At Allmatters, we offer period underwear in two different absorbency levels, so you can choose the model that best suits your flow.
Benefits of period underwear
Period underwear has many benefits. Here are some of the key ones:
• A sustainable choice: Period underwear reduces the amount of waste from disposable products like tampons and pads. By using our reusable underwear, you minimize your environmental impact.
• Economic advantage: Although the initial cost of period underwear is higher than, for example, a pack of pads, you save money in the long run as they can be used over and over again.
• Comfort and convenience: The underwear is designed to be as comfortable as regular underwear. With two different absorbency levels, you can choose the type that best suits your needs, whether you have a light or heavy flow.
• Easy maintenance: The underwear is easy to use and requires minimal maintenance. After use, rinse them in cold water, wash with mild soap or in the machine at 30 degrees, and they are ready to use again once dry.
How many pairs of period underwear do I need?
The number of period underwear you need depends on your flow and how often you want to wash them. A general rule of thumb is to have between 3-4 pairs. This number allows you to change underwear every 8-12 hours, which is our recommended usage time for optimal hygiene and comfort. By having multiple pairs, you can easily switch to a clean pair while the used underwear is being washed and dried.
How long can you wear period underwear?
Period underwear can be worn as long as your flow allows, but for a maximum of 12 hours at a time. Some prefer to use them during the day, while others use them as extra protection along with a menstrual cup or tampon. Generally, it is recommended to use the underwear for 8-12 hours for maximum protection and comfort.
You can also use the underwear at night, for spotting between periods, or for discharge. To ensure that the underwear provides the best protection, you should regularly check if they start to feel wet or if blood is visible at the seams - this is a sign that it is time to change them.
