Guide to Period Underwear: Everything you need to know

Period underwear is the perfect solution for women who want to feel comfortable, confident and secure during menstruation. It's also great for people who have sensitive skin, or if you're planning a big night out and don't want to worry about your period leaking through your clothes (or worse).

Period underwear works by using multiple layers of absorbent, moisture-wicking, and leak-proof materials to collect and hold menstrual blood. It's a reusable, eco-friendly, and comfortable alternative to traditional period products like pads, tampons, or menstrual cups. Just wear, wash, and reuse!

What is period underwear?

Period underwear, also known as menstrual underwear, is a type of reusable, eco-friendly undergarment designed specifically for wearing during menstruation. These innovative panties feature built-in layers of absorbent, moisture-wicking, and leak-proof materials to collect and contain menstrual blood, providing an alternative to disposable pads, tampons, or menstrual cups.

Choosing the right period underwear

When you're shopping for period underwear, there are a few key things to look for:

  • Size: If you're buying your first pair of period underwear, it's important to find out what size will fit you best. You may want to try on different styles and sizes before deciding on a final purchase.
  • Style: There are many different styles of period underwear available today--some more modern than others! If you want something simple and classic, then consider buying bikinis or high waist. For something more fashion-forward and unique in appearance, go with lace trimming or other decorative details like bows or flowers printed onto the fabric of your panties as an alternative option instead!
  • Material: The choice of material is a significant consideration. At AllMatters, our period underwear is crafted from TENCEL™, a sustainable material derived from FSC-approved wood fibers. This makes our product not only eco-friendly but also incredibly comfortable. Additionally, the gusset is made from merino wool, which is naturally antibacterial, offering you an extra layer of protection and hygiene.

Benefits of wearing period underwear

Wearing period underwear offers several benefits, making it an appealing choice for menstrual management:

  • Eco-friendly: By choosing reusable period underwear, you are reducing the waste created by disposable menstrual products, contributing to a greener planet. Check out our commitment to sustainability here.
  • Cost-effective: Though the initial investment may be higher, period underwear saves money over time as it can last for several years with proper care
  • Comfortable: With no uncomfortable inserts or adhesives, period underwear provides a seamless and comfortable experience.
  • Chemical-free: Many period panties are made of organic, hypoallergenic materials, reducing the risk of irritation and allergic reactions.
  • Versatile: Period underwear can be worn alone or as backup protection alongside other menstrual products, offering peace of mind during your cycle.

Caring for period underwear

Caring for your period underwear is easy and can be done in the same way that you care for other clothing. You just need to know what to do with them when they're dirty, and how to wash them properly.

  • Wash your period underwear in cold water on a gentle cycle or by hand.
  • Hang dry or dry flat if using a machine dryer (hang drying is best). Do not tumble-dry! Tumble drying may shrink the fabric and make it stiffer than intended, which could cause discomfort during wear.


If you're looking for a way to make your period easier and more comfortable, period underwear is the right choice. It's easy to use, comfortable and discreet. You can even wear them without anyone knowing they're there! Plus, they have many other benefits such as reducing leaks or saving money on pads or tampons while helping the environment at the same time.
