This harness is designed for workers climbing cell phone, TV, radio and utility towers, while building/decommissioning towers, changing out transmission lines/antennas, or installing/replacing lights. The breathable, open-core padding technology provides optimal air flow, while reducing heat and moisture entrapment, keeping a worker drier and cooler. DuraFlex® stretchable webbing provides greater flexibility and increased comfort. New cam buckles on the shoulder straps make vertical webbing adjustment easy.
