Care instructions

Did you know that in a lifetime, an average of 10,000 menstrual products are used that then end up in the trash? That’s a lot of full trash cans. This menstrual underwear is durable in use and lasts at least 30 washes.
  • First rinse the underwear under the tap.
  • Then wash it at a maximum of 40 degrees in the washing machine (without fabric softener).
  • Hang it out to dry. Do not put it in the dryer. The absorbent layer takes one to two days after washing to dry completely. We therefore recommend that you wear different ones during your menstrual week.
  • The absorbent layer softens after washing.

How it works

Let’s take a closer look at our ultra-thin, super absorbing technology. It consists of 4 layers. All the layers are incapsulated with glue to ensure they stay attached to each other. Additional stitches keep the inner gusset in place and ensure durability. The glue makes sure no blood can come through the stitch holes. When we say no leaks we mean no leaks!
