    Comfortable, good for running

    I'm an adult, but ordered the size medium (usually I'm an XS in adult sizes) and the fit was good. I've mostly worn these under my leggings for running, and they are comfortable.

    A Must Have!

    Theses were a part of a 3 pack and an excellent value. They are very comfortable and do the job. I highly recommend them. They work wonders for my post menopause leaks.

    anti-chafing comfort

    These are very comfortable under skirts & dresses for preventing thigh chafing and for modesty when the wind blows.

    Parfait!

    Il semblait court à première vue mais non il est parfait. Très léger et confortable. Parfait pour porter sous une robe ou une jupe.

    I don't love them

    These aren’t as comfortable as my other boyshort Knix pairs that are quite similar. The legs tend to ride up and don’t stay in place, which kind of defeats the purpose of why I chose this style in the first place.
