    Great feel and comfort but limited color options

    I love the comfort and feel of these underwear and love the protection they provide. I only wish they had more color options available.

    Cotton and comfortable!

    I am all about cotton! I was so glad to find cotton leakproof undies! I found another brand that was so uncomfortable (like a diaper) . Thank goodness I found the Knix highrise cotton—so so comfortable. They are as comfortable as my most comfortable pair of regular undies!

    Doing the trick and fitting right

    As a larger bottom (bubble butt) lady, these cotton undies fit me best. No issues. Wearing for swear absorption, hello 40!

    Not as described

    The smell does not come out when you wash them. One wearing and they are done. Very expensive to only be able to wear them once.
