The "Cure" lumbar pack from Blacks Creek is definitely a one of a kind and the cure to what ails you! No other pack on the market today has a removable suspension that allows you the comfort of a lumbar pack along with the ability to haul out large loads in the meat carrying suspension. The harness has a webbing system that allows you the ability to manipulate your heavy load. By doing this, it helps keep you from exhausting your muscles and becoming fatigued. We believe we've definitely hit the ball out of the park with this new pack design.
