    After buying two Zone+ panties I loved them so much that I bought three more. These panties make me feel secure with my heavy flow.

    Disappointing

    Honestly I've tried every type of leak proof but these unfortunately were terrible

    The gusset is very narrow between my legs and leaks horribly. The gusset is short infront, so you get leakage there too. This picture is the same size gusset. I couldn't find a zones picture. The pink is an overnight example with the full coverage cotton leakproof. Sorry for the realistic pics but the gusset needs to be wider on the sides, higher in front and back and more leak proof. I bought medium because small was too tight near my thighs. Medium gaps but the company doesn't help with any other options cuz there's no other options.

    Sizing off

    The new longer, full back panel is interesting. But please note it is not as expandable as the basic pant, therefore the pants do not fit as well. I am a large lady but you 3X as always been fine for me plus I've lost weight recently. I was very surprised to find my new KNIX did not fit as comfortably. I now have 5 paitrs that I prefer not to wear. Disappointing.

    Am sold on these!

    I am using these for OAB and use pads with them. So far have been the best I have found! Am just amazed at sizes though.

    Bizarre

    I bought these a while ago and I was looking forward to having something I could wear when my period is insanely heavy. These are not that. The leakproof portion goes up the entire back and no matter what you wear them under it looks like your wearing a diaper.

    So I figured, okay I guess I can wear them to sleep and lounging around the house, but leakproof portion is stiff and uncomfortable and feels like some sort of weird soft helmet for your coochie and butt. Cannot recommend, do not buy them.

    Bulky

    Bulky and extra padding for leaks is in the back. It is need on the front for bladder leakage. These have panty lines. Feel like I am wearing a tight backward diaper.

    Love them and feel safe when wearing them.

    Why is white not an option. Sometimes I need white 🤔

    Great product

    I already have several pair of the knix underwear that I have been wearing for bladder leaks. This order is actually for a smaller size and the new heavier style . The KNIX underwear have been a blessing. I plan to order 3 more pair in a couple of weeks .
