Easily adjustable and versatile full body harness for use on high rope courses. The different colors of the shoulder, hip and leg straps make the harness intuitive to put on and enable trainers to check it quickly and reliably. The eight Slide Block buckles enable the fit of the harness to be optimally adjusted for a wide range of user heights and sizes. Thanks to the dorsal eyelet certified to EN 361, the RADIALIS AIR offers an additional attachment point, for example for use with pamper pole elements. The labeling field and integrated RFID transponder can be used to personalize the harness and make it far easier to document its use.
