FEWER SEAMS, BIGGER SWEET SPOT.Tech innovation arrives on the pitch in the Nike Merlin Football. Taking traditional 12 panel construction to a 4 panel configuration substantially reduces seams and opens up a wider striking surface. Aerowtrac grooves keep the ball flying where you want it to go, while 3D ink patterns strategically raise the texture in certain zones for enhanced boot to ball interaction. 4 panel construction reduces seams and enlarges the striking surface. 3D ink patterns apply variations in texture for targeted control. Nike Aerowtrac grooves allow consistency in ball spin. Foam casing consists of multiple layers of polyurethane bonded together with a cloth backer. Latex bladder wrapped in cloth maintains air pressure more consistently than traditional rubber bladders, keeping the ball shape spherical.Material: 37% SYNTHETIC LEATHER. 33% RUBBER. 20% POLYESTER. 10% COTTON.
