The Leopard3 is a flatter, faster Leopard. Very controllable right out of the box. The Glow Champion Line is made with the same high-tech durable plastic as the Champion Line with the added benefit of glowing in the dark. Glow Champion discs are easily distinguished by their translucent greeish-yellow hue. Highly durable and easy to spot, the Champion Glow Line is perfect for Glow Disc Golf.
