Our high performance bands are designed with a large OD tubing to reduce the pressure felt on your shooting hand. Utilizing a high stretch ratio to maximize the power stroke, our high performance bands deliver the maximum power and speed from your polespear. A two loop system works exactly like a single loop, but allows the bands to be stored in a polespear bag without folding them in half. Bands are custom built for your spear and draw weight and can be built for any spear. Certain draw weights may not be possible for every length spear. High performance bands are most commonly used for 6 to 8 foot spears with draw weights of 35-45 pounds. Please send a message after ordering to confirm specs.
