Hello, I wanted to tell anyone who is still using tampons and sanitary towels/pads about period pants. I think they're a total game changer for women and for the environment. They look and feel like normal pants, but with a slightly thicker lining. You can get various absorbency in some brands. You don't need a tampon/towel or anything as back up. They will last all day or all night. Rinse them out when you take them off then you can machine wash them with your other washing.
I've uploaded a video to YouTube to show how mine coped with 10 hours of heavy flow (content warning: menstrual blood, obviously)
