    Always love French cut!

    Fit better than regular as my thighs enjoy the high cut. So no show under pants!

    Always my go to for fit.

    I am 68, so a bit of bladder protection is good.

    Great

    Comfortable, good looking and efficient. I use it to avoid humidity and sweat from reaching tight or light pants, great for leggings.

    Good offer but…

    This was a good offer but even if it was mentioned in the ad that it was mix Colors, in the 3 packs I ordered I received 2 pairs of bright yellow, 1 pair bright red, and one pair mustard. My friend ordered the same product but she received more neutral colors.

    I will not order this kit again.
