So I had already some kneepads (worn), but now times have convinced me completely. First, fit the complete them out close to the knee pockets of my work pants, secondly, do not break the parts already after 2 weeks and yet I forgot when washing, are after 3 months construction site and at least 10 times washing (I knew then that the enduring * G *) is still as good as on the first day. And that most important, the price is really reasonable. This has even drove me to the idea to equip all pants with the parts and not always just to switch. Another advantage is, they press the trousers at the knee outwards. So if you come once a real sweat, is supposed to occur in construction, so dry the trousers at the knee again. Even with the 'old' knee pads elasticity has not taken off.
