Familiarity: I've put it through the wringer
Great material, almost silk like. Does not retain heat. I do not notice them while riding.
I had a bad knee replacement. The sleeve around my knee combined with CBD oil is a great help. Even in the heat of the summer the knee skins feel good. Highly recommended.
