Construction
Outer Covering

Synthetic Cover- The best qualities balls are covered with a synthetic leather material which offers superior feel and softness but are less water resistant and durable. More Expensive.
Polyurethane Cover- These better balls are covered with a synthetic material and offer a feel similar to leather. More water and scuff resistant
PVC Cover- Least expensive ball molded out of a PVC material that is plastic like. They are the most durable ball but usually the least popular because of the feel.

Bladder Types

Latex - gives the ball the most lively play and good feel but has the least air retention.
Butyl - better air retention and is the most common

Stitching
Today, most soccer balls are machined stitched and hold up quite nicely. You can still find hand stitched soccer balls but expect to pay a lot more.

Deflate Match Soccer Balls slightly after use. Before inflating any soccer ball, give the needle valve a shot of silicone to help keep it moist.
