HER Period Underwear Guide & FAQs

1. What are menstrual or period underwear?
2. How do I care for my period undies?
Washing your undies shouldn't be complicated, so we designed our products to be super easy to wash.
Step 1. Wash the undies before wearing them for the first time for maximum absorbency during personal use.

Step 2. After use, rinse in cold water (<30°) until water runs clear.

Step 3. Wash in cold water with a mild detergent — right away or later, whatever works for you. Hand washing is great, but machine washing is totally okay too!

Step 4. Hang to dry (preferably under the sun).

3. What are the differences between your undies' styles and absorbency capacity?
Light Flow: Our Classic Period Underwear absorbs 20–40ml (about 1–2 pads or tampons). Perfect for lighter days.
Moderate Flow: Our Mid-Waist Period Underwear holds 30–50ml and absorbs faster than the Classic. Great for regular flow days.
Moderate to Heavy Flow: Our Seamless Period Underwear and Period Shorts can absorb 40–60ml. Designed with special fabric to lock in moisture better — perfect for heavier days.
Note: Our undies are designed to be super reliable, but every period is unique.
If you have a heavy flow, you might want to mix and match with our Pads, Cup, or Disc for extra backup!
4. Is it free of harmful chemicals?
Absolutely! We care deeply about your health and safety. That’s why all of our products are made with safe, eco-friendly materials. Our Period Underwear is tested and approved by OEKO-TEX (Switzerland), meeting strict human-ecological standards for your peace of mind.
5. Can this replace my usual period protection routine?
Yes! Every period is different, and how you use our products depends on your flow.
Feel free to mix and match to find what suits you best!
6. Where else can I use these underwear?
Our period underwear isn’t just for regular periods. They’re also great for prenatal care, postpartum discharge, irregular menstruation, and even light urinary incontinence.
7. What is the lifespan of your period underwear?
With proper care, our period underwear can last up to 5 years — made to stay with you through every cycle.
8. How do I store my period undies?
Make sure your period underwear is completely dry, then simply store them in your regular underwear drawer — easy and ready for next time!
9. How can I change them when I'm outside?
Just bring an extra pair with you! When it’s time to change, swap them out like regular underwear and place the used pair in your dry pouch until you can wash them.
