The insertion of the cushion in the Blåkläder trousers is somewhat tricky, but they fit exactly and then can no longer slip. While wearing you realize they hardly and the knees are fantastically comfortable. One can easily drop to his knees! I knew previously only knee pads, you juts from the outside over her knee and buttoned with a rubber band on the back of the knee - who cut are runtergeruscht and you were lucky if you had once found a comfortable position. Since these pads are of an entirely different class Blåkläder, where you can work just about anywhere kneeling without thinking. But despite the euphoria after a day laying of paving I will not conceal two small downsides: - The little instruction booklet is tiny with tiny letters (but in many languages). It was difficult to find out in which direction (up, down, front, back) the cushion to be used. - The pads have a tendency to align straight as a board. The result is that the pants are spanned quite broad in the calf area. (But that's just an aesthetic feature.)
