The surface or the outer of a football is made up of synthetic leather and not full grain leather (As used in years gone by). Leather has a tendency to soak up water causing the football to become very heavy. Synthetic leathers are typically made from two materials – PU (polyurethane) and PVC (polyvinyl chloride).
The inside of the football is made up of a latex or butyl rubber bladder which enables the football to be pressurised. The ball's outside is made of leather, synthetic leather, polyurethane or PVC panels. The surface can be textured, weaved or embossed for greater control and touch.
