The RETRO SERIES Punching Wrecking Ball is made from dark tan colored marble grain leather and reinforced with synthetic leather cross fiber bonded black panels for extra strength. It is a robust club bag that can withstand regular and intense workout sessions. The bag features 4 heavy gauge D-Ring hangers that are attached with double layers of leather and nylon webbed strapping, which is cross-stitched into the main material of the bag for added durability. The bag can be filled and sealed securely with a heavy-duty zip. The bag is great for combination with footwork movement, balance, and timing.
