AllMatters Period Underwear


The AllMatters Period underwear feels and looks much like your regular underwear, but with builtin layers of high-tech materials that all serve different purposes from absorbing your flow to making you feel safe during your menstrual cycle. Depending on your flow, period underwear can be used instead of a menstrual cup, pads or tampons or along with a cup for extra security.

The period underwear allows those interested in switching to a reusable period product but not too keen on something that is inserted (like the cup), to also access a comfortable and conscious alternative to conventional products.

How does it work:

Step 1: Use period underwear instead of a cup, pads, or tampons or as a backup for extra protection (depending on your flow).

Step 2: After use, rinse in cold water until it runs clear. Machine wash cold (30°) or by hand with a mild detergent. Hang to dry.

Step 3: Reuse and repeat. Period underwear can be used during the day and night.
