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.

Best eco friendly underwear

I have a few from different brands but these are my favourite. When will you stock up. What to get a second pair.

Impressed

There was a small amount of leaking at the seams the first few wears but after a few washes this stopped and the absorbency seemed to dramatically improve and they’re really good. Super comfy too and love the clips.

High expectation… fulfilled! - Grandi aspettative… soddisfatte!

I met fluxundies.com thanks to this underpant’s type whose practicality impressed me: I was searching for an absorbency slip, useful for those times I realize my period start unexpectedly, with in intention, at the same time, to replace completely disposable pads. The lateral closing on the both sides ensures this practicality that is very useful when I am away from home. I am very satisfied with my purchase… I hope that it will restocked soon.

Ho conosciuto fluxundies.com grazie a questo tipo di slip che per la sua praticità mi aveva colpito: cercavo infatti uno slip assorbente utile per quando mi accorgo inaspettatamente di avere le mestruazioni, volendo, allo stesso tempo, sostituire completamente gli assorbenti usa e getta. La chiusura laterale da entrambi i lati assicura questa comodità che si rivela utilissima quando sono fuori casa. Sono veramente soddisfatta del mio acquisto… spero venga riassortito presto.

Very poor quality

These arrived already broken away from the clasp on one side, and hanging by a thread on the other. I never even got chance to put them on.

Very slow response from customer services. They asked me to send them back at my own expense and they would send a replacement. No apology, no offer of refund or new item. Disappointed with both quality and customer service.

I didn’t want to throw good money after bad so I’ve just left it. However I have no faith in this company or product.

Best material quality. One panties holds whole day without one drop of blood on your pants. I don't even know that I am in my days, very comfortable and light. You don't have to be worried that something is visible or uncomfortable like with classic pads.

stylish bikini period undies

I bought these undies as I find period high waist briefs uncomfortable. My belly get really bloated on my period due to endometriosis.
I found this pair is really absorbing and looks great. The only flaw I found with it is the side clasps are tight and mark my skin. I am hoping they will loosen with time and perhaps I will buy my next one in a larger size to avoid for this to happen.
