Footbag is a growing
sport, played mostly in Europe and North
America, though there are a rapidly growing number of footbag clubs and players around the world. Frequently referred to as "Hacky Sack" (a product manufactured by
Wham-O, Inc.), footbag has existed as a competitive sport in several forms since the 1970'
s. There are a substantial number of footbag tournaments and festivals each year.
Competitive footbag is governed by the International Footbag Committee (IFC), which publishes the official Rules of Footbag Sports.
