Leak free, odour free and worry free

We have tested our Emflower Period Underwear over and over again, to ensure the 4 layers of technology within the material will be consistently leak free, odour free and maintain its elasticity wash after wash.
With proper laundry care, Emflower Period Underwear will easily last you many years and up to 90 machine cycle washes.
We guarantee Emflower Period Underwear can hold a minimum of 4 regular tampons, or roughly 25ml of liquid. See the info-graphic below to learn how the 4 layers of technology work within our Period Underwear:

  4. Hang dry your Period Underwear. Do not put them in a dryer or iron them.
  5. Do not use fabric softener or bleach on your Period Underwear.

Check out the common questions we get asked at Emflower about our Period Underwear:

How many hours can I wear my Period Underwear for?

Well that depends on how heavy your period is. Our Period Underwear hold up to 4 tampons worth, which is equivalent to 1 day with a medium to heavy period. If you generally use more than 4 tampons during the day, make sure you keep a spare pair of Period Underwear in your bag just in case.

Will my Period Underwear stain?

To decrease the chance of your Period Underwear staining, make sure you rinse or soak them within 24 hours after wearing them. If you are not doing washing for a couple of days, leave them soaking in a bucket of water with a little bit of laundry detergent.

Do not use bleach on your Period Underwear, as we use a plant-based dye to colour the underwear and bleach will strip this colour.

How many pairs of Period Underwear do I need?

That depends on how long your period lasts, and how heavy it is. We recommend changing your Period Underwear each day and night for heavier periods. So if your period usually lasts 4 days, we would recommend 8 pairs of Period Underwear. When your period is medium to light you could easily get away with wearing 1 pair for up to 24 hours.

Can I wear Period Underwear with other menstrual products?

Yes you certainly can. For those with heavier periods, we recommend pairing your Period Undies with a menstrual cup for that extra protection. They can also be worn with tampons and pads, but in all honestly they don’t need to be. They have 4 layers of protection so you should be more than fine to just wear your Period Underwear by themselves, unless you have a really heavy flow.

Can I wear Period Underwear Swimming?

Unfortunately you cannot wear your Period Underwear swimming. Those 4 layers holding it all in will definitely leak out into the pool or ocean. We recommend using a menstrual cup when you go swimming, as you will be fully protected from leaks.

Bought it for my friends daughter & she loves it!


My daughter said it was great.


Bought these as a gift for my younger sister as i already use the menstrual cup. She absolutely loves these! Fits her perfectly, feels comfortable and easy to wash. She said these saved her during an exam on a day she wasn’t expecting her period ☺️
Highly recommend!
