“Mine came today, I ordered 2 pairs first to make sure they fit and they’re super comfy! Just ordered 4 more 👏🏼”
“LOVE LOVE LOVE my new 2-4-1 period underwear. I’ve always been hesitant worrying about leakage, comfort and absorbency but these are perfect. Super soft and comfy, don’t slide down, no leaks or awkward VLP in leggings AND good for the environment too; no need for tampons/pads again!”
Amy Webb
“Where were these 20 years ago! These have utterly change my life - they are comfortable and that supporting for that time when you need that additional security! I’ll be buying these in black when available in my size! Don’t deliberate on these- they are worth all of your money! Saves so much money on pads and washing clothes!”
“Love them, my periods have always been pretty heavy and it's always made me feel anxious about potential accidents but while wearing these I haven't been so anxious about wearing light coloured clothes so i'm mega satisfied!”

How do I wash my Period Pants?
The best way to care for your period pants is to first rinse them in cold water in the sink.

After that, you can either hand wash with detergent (this will make them last longer) or wash them in the washing machine in a gentle, cold wash (30°).

They can be washed with your other clothes, so no need to put on a separate wash!

Do not tumble dry and if you can, skip the fabric softener🙅‍♀️!

Umm... I have a question?

If you can't find your answer here, please email and our customer love team will have the answer you need.

How often do you change period pants?
We found that most people use one pair during the day and one during the night, but it all depends on your menstrual FLO! 🩸

If you get through more than 5 tampons a day, we recommend doubling up and using your pants plus an organic tampon/pad!
Will I just be sitting in my period blood with period pants?
Before many people try period pants they wonder this but thanks to the magical gusset 🪄 your blood is pulled into the absorbent layer keeping you comfortable and dry!
Can you use period pants with heavy periods?
If you have a heavy flow we recommend doubling up on products (especially overnight 🌙), e.g tampon & period pants and seeing how you get on
What happens to blood clots when wearing period pants?
If you have the odd blood clot during your heavier days (if this is often please see a doctor 👩‍⚕️) these cannot be wicked up by the top layer of the period pants. Simply wipe this with a tissue and carry on your day.
How did the Netflix Sex Education collaboration happen?
It all started because Netflix’s HQ was offering FLO period products in their office team & staff bathrooms!

Someone from their partnerships department recognised that both we and the Sex Education series had a knack for opening messy, fun & empowering conversations and reached out to us for the ☁️ collaboration of dreams☁️.

Almost 2 years later and we’re finally in stores worldwide! 🙌
Can I swim in my period pants?
We are afraid not!

Even though our period underwear has leak-proof magical gusset, it won't keep you protected from leaks while swimming! 🏊‍♂️

Similarly to period pads, period underwear is worn on the outside of your body meaning it will soak up water while swimming and will leave you with surrounded by a red cloud🩸.
Will you be releasing a range without Netflix branding?
