Why Slackline in a Gym When You Could Slackline Over a Waterfall in Hawaii?

At just 19 years old, is one of the youngest phenoms in slacklining. He’s traversed the globe to compete, winning the Teva World Cup and the Slackline World Championships, all before he graduated high school. For his biggest project yet, he teamed up with his mentor, , and a Redbull film crew to trickline his way through the world’s first “slackladder” — a term coined by Redbull. In June, their crew of about 25 people headed for Hawaii’s Big Island to spend four days constructing the ladder, a series of 12 slacklines and other obstacles strung together to ascend a waterfall.
A far cry from the loud slackline competitions Mason is used to, the jungle of Hilo provided a serene backdrop for . ϳԹ caught up with Mason and Lewis to learn more about their motivation for the project, and find out what’s next for the sport of slacklining.

Performing for a camera is completely different than the crowds Mason is used to, but he says he harnessed the solitude of the Hawaiian jungle. “I was much more focused than if I was in front of 1,000 people.”

Mason belongs to a new breed of professional slackliners. He says his mission is to raise the level of slacklining, and spread the sport as much as possible.

Mason sees the project finally come to fruition after a year and a half of planning.
