    Love these for under dresses and skirts. I sized up for a more comfy fit, but definitely could have stayed true to size.

    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.
