    Love these!!

    I love these panties. I love that they are more breathable because they are cotton then the regular panties.

    I bought some for my daughter for Christmas. That was her one complaint about the Knix. They are hot and sweatie. These are brilliant that the pad is sew in but separate. I think these are my favourite!
