I'm thoroughly impressed with these. Excellent quality and absorbency; they last all day even on day 1 and 2 of my period! They're so absorbent that, despite regular "gush" moments, I feel dry again shortly afterwards and I don't have that awful feeling that pads give, where you're basically sitting in a wet nappy. They're so thin, too! You could get away with wearing them under leggings too, if it weren't for the seams around the absorbent section which do show through a little bit. Still, far better than reusable pads I've used previously, which are super bulky. They come up quite high on my body (to my belly button), which I thought I'd hate, but turns out it's actually super comfy and feels like it supports my bloated period belly without compressing it. I have a short torso, so maybe they wouldn't come up as high on everybody.
I'm currently in the midst of my 2nd natural period I've had since quitting the contraceptive pill, so my flow is quite unpredictable at the moment. But so far these pants have not let me down and I really trust them!
