Must be worn with a sit harness. Do not use a chest harness alone! Singing Rock Arbo Chest Harness is a lightweight chest harness designed to improve support, comfort, and efficiency when climbing, particularly in SRT systems. Developed for use with Singing Rock arborist harnesses, it is also compatible with other models, such as the DMM Kinisi, provided the harness has three suitable attachment points. The design helps stabilise the system when carrying heavier equipment and improves body position during ascent, reducing fatigue over longer climbs. Padded shoulder straps include integrated tunnels for routing a pull-on elastic, supporting efficient SRT setup, while front attachment loops allow for fitting a chest ascender and organising additional equipment. A front-mounted whistle is integrated for convenience, and the harness is easy to don and adjust for a secure, comfortable fit in professional tree work applications.
