I have had knee issues for the past 20 years... so always looking for new knee support that is light weight and does not show while wearing slacks! These work very well easy to slide on, tight enough, does not slide down like others where I had to readjust 1 to 2 times and hour. Breathable material so not collecting sweat on the back of my legs. Have only had them about a week and no complaints, as of now... let's see how the hold up to daily use!
