\Has ‘double stuff’, two layers of 1/2" padding, for extra comfort and single 3/4" wide leather buckle straps. Top quality cowhide from very giving cows lined with felt padding. Each knee pad has two 1" deep x 4" wide U-shaped notches in the top and bottom edges to permit a better fit above the knee and on the shin. This makes the knee pad less susceptible to shifting and more comfortable to wear when standing.
