FIVB-approved beach volleyball ball; Spherical, made of flexible material (leather or synthetic leather); Circumference: 66–68 cm (slightly larger than indoor volleyball)
Why people argue about this
People often assume that since beach volleyball is played in sand, the ball must be yellow like most other beach sports' balls. But actually, NCAA rules specify these balls need to be FIVB-approved AND have a color and pattern approved by the NCAA specifically for college play, which can lead to confusion about what exactly qualifies as 'approved.
