Cassie Sharpe brings qualities to women's halfpipe skiing that haven't been seen on a skier since the late Sarah Burke. Shredding fearlessly and learning at a voracious rate, Cassie put her stamp on the industry with a booming win at the SFR Finals in 2015. Boasting amplitude that doubled and tripled some of the other athletes, Cassie took the win and unceremoniously took the reins of the sport from them. Making sure she wasn't a one-hit wonder, Cassie won the inaugural Winter X Games in Oslo in similar fashion. In a discipline that's mired in a rut, Cassie has come to lift the sport, push the other athletes and build a legacy of her own.
