Conforms to EN 14404:2004, PSA Type 1. Protects and is also gentle to the knees! The knee protector was developed in cooperation with the "personal protective equipment" technical committee of the German central federation of industrial professional associations. Thanks to its design as a torsion spring (optimised pressure distribution) and the special material composition (PUR with micro-air absorption) the strain on the knee joints and the ligaments is noticeably relieved – this effectively prevents subsequent injury! The knee protector is simply affixed below the knee joint with a Velcro fastener, quickly and securely. It allows maximum freedom of movement whilst remaining very easy to handle. Thanks to the large and elastic surface, no marks are left on soft floor coverings. It also offers protection against damp and dirt and is easy to clean. A trulyworthwhile investment in your health!
