Softball equipment protects you from being seriously injured while playing.

Bats in slow-pitch and fast-pitch come in all different lengths and weights.  In fast-pitch a lighter bat works better, so you swing faster.  Most bats are made of aluminum, alloy, or graphite.

Helmets in softball are required.  This protects you from the chance of getting hit in the head with a ball.  In fast-pitch it is required (in some areas) to have a safety cage on your helmet.  In slow-pitch you are not required to have a safety cage.

Catchers are required to wear a face mask, chest protector, throat protector (attached to chest protector), and shin protectors.  When a play is at home the shin protectors protect their legs from sliding cleats of the offensive player, also if they are hit by a pitch when catching.  The mask and chest protector keep the ball from breaking any bones in the face or chest when catching. 

Bases are a big part of the infield.   Home plate is a white rubber pentagon surrounded by 7 foot by 3 foot rectangles, also called the batters box.  First base is sometimes a double bag.  A double bag has two bases instead of one.  The orange bag if for the runner and the white one is for the infielder, this helps prevent many collisions.  But sometimes they just have the plain rubber first base.  Second and Third base are white or yellow rubber squares that are 15 inches length and width and 5 inches thick.  

*Mouth pieces are optional in softball.  They help keep your teeth in place if you are hit by a line drive. 

*Sliding pants, knee guards, arm guards, leg guards, and ankle guards are optional for fielding, batting and sliding.  These guards help protect and prevent common sliding injuries and serious fielding ones.
