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
I bought these more so to stop accidents as I have a super heavy flow due to fibroids. So I use with a sanitary towel, and if there are any leaks, they’re not now going through to my clothes, so I’m very happy. The style is very cool also, a massive step up from the giant pants that I’m used to being stuck with for 6 days! Brilliant purchase

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.

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 :)))
