    Light as air

    I thought these would be thick and heavy. Quite the opposite is true, they're silky and light. More like lingerie.

    Love them!

    Love the thigh savers! I recently turned 59 and my comment to friends was that you know you’re getting old when you buy leakproof underwear! Happy this is an option as I’m not ready for the alternative. They are so soft and silky too.

    Overall Happy

    Great pair of underwear for minor bladder leakage front to back panel exceptional. Modern design and style, overall very comfortable. Just wish there was extra lower rear end coverage as cut in back is high. Fabric is light, cooling and discreet under clothing.

    6” thigh saver is great!

    The 6” thigh saver is very comfortable to wear and true to size. They maintain their size after washing and drying.

    Perfect for traveling

    I love these for so many reasons. The fit is perfect, the material feels soft and silky. It is so thin it feels almost like I am wearing nothing, plus it doesn't add bulk. My pants/jeans slide right on. I bought one to try it. I now own nine pairs.

    They are perfect for traveling because they take up so little space, are easy to hand wash and dry quickly. Plus, I have the extra security, when looking for a public restroom, that any small urine leaks are covered. I'm going to be purchasing more for my next long cruise.

    Love these

    Comfortable every day wear! Perfect for spring and summer!! They don’t ride up at all! Honestly would love if they had a little tummy control. I tried the ones with a little control but those actually did roll up on the thighs. Love the actual body shapers but they are definitely not for daily wear

    Soft fabric

    These shorts are soft and cool and comfortable to wear. I probably should have gone down a size, because they're a little slippery, but they are still a very nice short.
