How They Work

Our period pants absorb up to 5 tampons' worth of liquid, yet they look and feel just like regular undies.

Our built-in tech works like this:

1. Top layer wicks moisture away from the surface quickly, to keep you dry

2. Our middle layers absorb your blood and lock in your flow

3. The bottom layer pushes liquid back up and keeps you leak-free

It's simple. Just wear, wash and reuse.

Blood, Sweat, Whatever.

I bought these to wear for the what if days. You know, when you feel like you might start your period but your not sure as your cycle is all over the place. When it’s not convenient to be popping to the loo frequently and carrying the menstrual cup in your pocket. These feel like normal pants but reassuring. I preferred the fit if the boy pants though.

So good I have ordered more

Very relaxing and felt secure. I feel like I’m in control and I had no concerns about leakage. Comfortable enough to wear night and day.

Life changing!

I bought flux undies to cope with light incontinence. I took them on holiday and they rinsed out and dried within a day. I used to have bouts of pruritis using panty liners but not any more.

Absolutely in LOVE!

Really really love this style. I can usually use the light versions for the majority of my period except for on the first day and love wearing this style because they make me feel sexy and look super cute! They don’t leak and I can tell when they’re almost full because they stop feeling dry but this is usually after a whole day of wearing them and feeling dry all day!! Amazing :)))

Just ok...

I was excited to use my new Flux panties this weekend and found some pros and cons...

Pro- fits true to size, comfy high waist.

Con- the pad isnt long enough in the front and leakage overflows through the panties. Also wish the material was more breathable and eco friendly.
