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.

Looks and sits perfectly

This review is about light absorbency panties. I have used these once so far, but they are quite comfortable, seem to be of a good quality and look amazing. Ordered another pair - that is how much I like these undies. Only thing I'd like improved is a choice of colours. Shipping/handling is super quick and nice service in general. Highly recommended!

how long can i wear them?

If cared for properly, our undies are likely to have a maximum tech performance of approximately 3 years. This means washing them on a 30-40 degree wash with the rest of your delicates, never using bleach or fabric softener, and hang drying! In terms of length of wear, we measure our undies by absorbency with our highest absorbency styles holding 4 tampons worth of fluid. For some customers, that means wearing them the whole day and for others that may mean carrying an extra pair of FLUX Undies as a backup. 

how do they work?

FLUX Undies are underwear that absorbs your period. Every pair is made with technology that absorbs your flow, wicks moisture, controls odour, and prevents leaks — leaving you fresh and dry. Take a look at our How it Works page to learn more.

how do i find the right size?

We recommend following the hip measurement, as most of our styles sit on the hips. Be sure to measure your hips at their widest point to find the most accurate size for you! In case you don't have a tape measure, you can use the size you usually are most comfortable with for your underwear. We recommend the undies fit snuggly, but not so tight that it's uncomfortable. For reference, you can check out our size chart.
