More About Bikini Reusable Period Underwear

Do your Reusable Period Underwear contain PFAS?

Rael is committed to providing safe and effective holistic cycle care. For more information on our Reusable Period Underwear, PFAS, and 3rd party testing, please refer to our blog post here.

How often should I change my period underwear?

Our panties are designed to be worn all day long – just like regular underwear – but the answer depends on your flow. We usually recommend wearing for 5-8 hours. However, if you’ve opted for a lower absorbency style, you might need to refresh after a few hours or use an extra bit of added protection (like a tampon or menstrual cup).

How much protection does the Reusable Period Underwear offer?

We offer three silhouettes for all your cycle needs: 

  • Bikini: absorbs up to 3 regular tampons
  • High Waist: absorbs 4-5 regular tampons
  • Boyshorts: absorbs up to 4-5 regular tampons 

While our Bikini style offers standard coverage, our High Waist and Boyshorts silhouette feature a gusset that extends to the back of the panty, guaranteeing all-day protection and coverage on even your heaviest days. 

I'm not sure about my size, what should I do?

We recommend taking measurements of your waist and hips and comparing those measurements to our size chart. When in doubt, size up! For more assistance with sizing, feel free to reach out to our Support Team at
