SIRRO 4 is the comfortable full-body harness without conventional 45 mm climbing webbing. It is particularly light and provides maximum wearing comfort. Optimum load distribution. The ring/triangle construction made from self-binding bands ensures an even load distribution in every fall direction. The rear suspension eyelet made from cross-bands supports the even load distribution in every fall direction. The four bands and two padded layers distribute the load. With the SIRRO 4, angled suspension eyelets transfer the load between the adjustable harness and the edge binding.
