The rules of cricket do not specify the material to be used in making a cricket ball. 
The best balls have a cork centre wrapped with twine, and a leather cover. 
The ball must be between 83/16 and 9 inches (22.4 and 22.9 centimetres) in circumference, 
and it must weigh between 51/2 and 53/4 ounces (155.9 and 163 grams).

The bat cannot be more than 38 inches (96.5 centimetres) long 
nor more than 41/4 inches (10.8 centimetres) wide at any point. 
It must be made of wood. The bat has a round handle and a flat, 
bladelike hitting surface.

Cricket players may wear peaked caps or helmets, open-necked shirts,
trousers, and spiked or crepe-soled shoes. 
Batsmen and wicketkeepers wear protective leg pads and gloves. 
Players who field close to the wicket may also wear such 
protective devices as shin-guards
