The ball has 4 layers including:
Grade 1 (Surface): The outer surface coating material provides high adhesion and soft feeling while maintaining rigid durability and abrasion resistance of Spalding balls.
Layer 2 (Glossy Body): The shadow body helps shape the structure, shape and protection of the internal components.
Grade 3 (Grade only): Nylon cord is wrapped around the ball to keep the round structure and durability of the ball.
Grade 4 (Ball inside): High-grade butyl inside the ball maintains air pressure in the ball, allowing the ball to have the necessary swelling and keep the ball slightly better.
