Soccer ball covers are meant to protect the construction of a ball, and make it more durable and long lasting. Manufacturers use two types of materials, mainly polyurethane (PU) or polyvinyl carbonate (PVC). PVC is the cheaper and much affordable variant, but it is more durable than PU. It has scuff-resistance, which makes it perfect for training soccer balls. PU is used for match balls, since it is softer than a PVC soccer ball and tends to respond better to contact.
The amount that you are willing to pay for the soccer ball might influence your search. These range in price depending on its type, make, quality and other features. If you are looking for a ball to kick around for fun or for a child as a toy, it is best that you opt for an inexpensive ball as they are likely to ruin the ball or easily get bored with it shortly after. This also applies to children who are in a league as they will soon outgrow the ball hence the need for a bigger and more expensive soccer ball.
