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
Products used:FLUX Undies, obvs!, Cloth pads, Menstrual cup
Good protection, not the comfiest
Bought light - flow thong to wear on day 5 of my period, and while it's great for absorbency (I feel 100% safe with no cup) the thickness of it is not ideal for a thong. It's not very comfortable compared to regular thongs or the other Flux undies I bought (hipster). I guess I should have expected as much! Might try the seamless thong one day, maybe they have less fabric... or maybe just give up on my dreams of wearing thongs while I'm bleeding!
These look very cute, especially the grey colour. I usually wears XS in all the other flux knickers and I generally wear a size 8 in knickers. These felt a little bit tight though I’m not sure if the S would have been too big. They’re still wearable for sure but not as consistent with the sizing as other flux knickers. I really love wearing them towards the end of my period when I’m not sure when it’ll actually end.
