    Comfortable Security

    Better confidence with the full coverage style. Very soft, comfortable fit. Does not show under most fitted clothing.

    Super plus leakproof

    I appreciate that this new brief can also be used for bladder leaks. I do find it a bit bulky though. I’m not sure if I need a small rather than a medium. I am worried the small may be too tight in the waist.

    Love these for anytime

    I find as I have gotten older things are changing. I love the fact that these go all the way up the back. Extra protection.

    Totally recommend these new underwear

    Super plus leakproof

    Love the idea of not having to use pads for protection and was hoping this underware was the solution. However for me they were not high rise enough, my waist is above my belly button and the legs are cut to high and I found I got a wedgy wearing them. Tried wearing them a little lower but still had issues with them riding up, for me they need to have more butt coverage. Love the fabric and the amount of padding but the fit was all wrong. Initially I purchased a large and thought maybe I didn’t have the correct size so exchanged them for an XL but they were to baggie in the butt and if pulled up to my waist I had them riding up into a wedgy.
