I was impressed how far up the back of the panty the absorbent pad comes up. I frequently get leaks in the middle of the night that regular pads don’t catch because of the position I sleep in. The part in the front doesn’t come up far enough for me. I would get a little bit of blood outside of the absorbent pad because I need it to come up farther (for my body). For reference, I do have very heavy and long periods. The style of the cotton versus nylon is different. The cotton comes up below my belly button like a comfortable bikini a bit higher. The nylon come up higher like a brief so my underwear would show a lot if I bent over. Both pairs are going to be great for me while I’m at home but not while being active
