    Good product overall

    Very comfy, just wish the cut didn’t ride so high on the bum. Would like more leak protection on the sides. Otherwise great!

    Heavy duty for bladder leaks

    I like wearing these when I know I will be in my car, possibly stuck in traffic and my bladder is talking to me. They are fairly thick and give coverage right up to the back waist. I find them a bit bulky under snug leggings and haven't tested them with a major bladder leak. They are more than I need for daily wear with minor bladder seepage. A nice, comfy and snug fit without being too tight.

    love them!

    Ever since I have discovered leakproof from Knix, I have ordered them whenever I see them on sale. I have heavier flow, the Ultra leakproof Zones+ are great. I don't usually have to worry about leakage in the front nor in the back. I feel better about minimizing my menstrual products garbage (like tampons & pads) by using these.

    Zones+ in error

    I wanted the Ultra Leakproof but ordered Zones+ by mistake for the kit of 3.
