A chest harness is worn around the shoulders, usually with a sit harness so as to provide an additional attachment point. This attachment point allows for better balance in some situations such as when carrying a heavy pack (as the centre of mass is below the connection to the rope) and when the person in the harness may be unable to maintain an upright position (due to injury or other influences).
It provides additional stability when climbing. Designed for indoor and institutional use, the harness features colour-coded nylon webbing to make it easier to put on. For adjustments, you can use the buckles. The harness must be worn with a sit harness. It cannot be used alone. A chest harness helps to stabilise the upper body.
