The STIHL elastic harness attachment is used in combination with the X-TREEm HT/HL shoulder harness and the ADVANCE X-FLEX waist belt (both sold separately), and is designed to make working with long reach pole pruners and hedge trimmers easier. When used in combination with the X-TREEm shoulder harness, the harness takes the weight of the machine and improves the manoeuvrability and user comfort over long work periods.
