    The back protection is spot on. The pad part is the perfect shape with high absorption. Perfect for sleep and travel days.

    Peace of mind

    Wow! This is the real thing. I wish that I had tried it years ago. Best period panty ever. Thus far I've only worn it with my most absorbent reusable period pad on my heaviest days even overnight. No leakage up the rear leading to lower back area because Knix has got you covered all the way up the back of the panties. No more losing sleep over leakage anxiety. The panties are reliable, look nice, are not bulky and dry relatively quickly.
