Its high density layered foam design makes the BLOCK Black Crossbow target the BEST crossbow target on the market. Open Layered Polyfusion Technology. - Easy Arrow Removal: Fusing the internal layers to the inner target wall results in more uniform layer compression which, in turn, means easier arrow removal. And, easier arrow removal means less shooter fatigue, which means you'll get more and better practice! - Longer target life: PolyFusion™ also results in longer target life. Because the layers are fused in place, they hold their position. Arrows find their way between layers. Previously, when an arrow hit a layer head-on, the layer would buckle. This resulted in layer damage that reduced target life. - Stops all broadheads & field tips! - Size: 16"x16"x12"
