It's hard to keep up with the speed with which freeskiers are evolving these days but we've got the latest in this video. Gus Kenworthy performs the first-ever double flip off a cannon rail. Mountainfilm's Executive Director, Peter Kenworthy - Gus's Dad - couldn't be more proud!
And congratulations to Gus on being part of the first U.S. National Half Pipe and Slopestyle Team hopefully headed for the Olympics in 2014!
Keep up with Gus and more great videos on his Facebook page.
