The Black Magic Tackle Harness - Standard is molded and contoured padded for a strong and lightweight harness. This harness divides the strain between the upper thigh/buttocks area and the lower back using twin element padded supports. This harness features free running lug clips that allow the load to be distributed evenly between the two elements of the harness. By having the angle of pull lower on the angler the pressure applied to the reel lugs is increased by up to 50% without any extra effort. Sizing: The size of the harness would depend on the physical size of the person wearing it. Our standard harness (683mm wide) would fit an average size person while the small harness (555mm wide) would suit a smaller person. We also have an XL wide harness (835mm wide) for the larger person
