Slackline Industries will back a series of professional slackline competitions in the U.S. this summer that is expected to draw competitive slackliners from around the world. The high-profile events comprise Dominion Riverrock Festival in Virginia on May 20-22, X Games in Texas on June 3-5 and GoPro Mountain Games in Colorado on June 9-12. The Colorado-based company has played a key role in pushing for a standardized scoring system known as the International Slackline Invitational (ISI) Rules and Regulations, enabling athletes and audiences to better understand competitions.
