    Works great but doesn't last long

    While my Knix are still better than disposable pads, they completely disintegrate after a year, despite careful washing and drying them flat.

    Silky smooth

    So comfy and silky smooth. Create a no show under clothing. Also provides just the right amount of leak protection for me. Definitely my new favourite.

    LOVE my Knix but….

    I have multiple pairs of these underwear and I love them, however, my only complaint is I wish the lined/absorbent part came up a bit higher in the front. I hope this is an option in the future for even the lighter absorbency options.

    Comfortable but gusset is too short

    Higher quality than my daily underwear. Washed well. Unfortunately, the gusset is a little short in the front which resulted in leakage. I would purchase for daily wear but not for period protection.

    Very comfortable and stylish, only wish the lining covered a little more in the front.
