Volleyballs are spherical in shape and typically comprise eighteen nearly rectangular panels made from synthetic or genuine leather.
In a break from the traditional construction, in 2008, the FIVB adopted as its official indoor ball a new Mikasa with dimples and only eight panels for a softer touch and truer flight.
Indoor volleyballs come in either a solid white color or the brightest shade of yellow.
They are produced in two variations: a youth version, slightly smaller and lighter than adult volleyballs, and a heavier "medicine ball" type designed for setters to enhance finger strength.
Beach volleyballs are slightly larger than standard indoor balls, featuring a coarser external texture and lower internal pressure.
