    Leaks out the back

    I got these for my 11 year old and she doesn't like them because they leak out the back. If the absorbant liner went up the back further they would be awesome.

    Not the best

    These were definitely a miss for my daughter. She has warn them a couple times and they have not provided her the right amount of protection.

    I’m not sure if it is because the pad isn’t full attached, but they do not work for her.

    Most Comfortable, BEST FIT

    Nothing makes me feel cleaner/dryer than cotton. It's the most comfortable and best fit for me by far. No rolling/sliding down. Everything stays put and keeps me feeling like it's any other day

    Bulky, but work

    These have a bulky, flappy seam as the front and back where the gusset is attached. I'm sure there is a reason for that, but I don't know what it could be and my Knix do not have that. My teen finds that very uncomfortable so I had to sew it down.

    That is the reason for the 3 stars.
