Yuki Kadono secured first place at the 2015 Air + Style in Los Angeles on 21 February with a switch backside triple cork 1620 - a first ever for the trick that puts him into the history books of snowboarding.

An estimated crowd of 25,000 watched the final of the Air + Style tour at the legendary Rose Bowl Stadium.

The third and final leg of the tour saw 16 of the world's best freestyle snowboarders compete for the "Ring of Glory" and a share of the $100,000 (£65,000) prize.

The 40m-high and 140m-long steel scaffolding jump offered the riders the best possible conditions and the level of freestyle snowboarding was pushed to new limits.

The riders picked up speeds of 70kph on the in-run with a 45 degree descent, as they catapulted themselves with impressive tricks into the LA night sky.

The main competition rankings focused on trick execution, style and height.

The Japanese snowboarder repeated his Air + Style Beijing triumph and reached new heights, becoming the first rider ever to land a switch backside triple cork 1620 in a contest.

Second place went to Canadian Sebastien Toutant, who made a clean backside triple cork 1440 in his best run.

Stale Sandbech clinched third place in the final with a backside 1440 but his third Air + Style podium this season was enough to give the Norwegian the overall Air + Style tour victory.

The Air + Style tour is a brainchild of Shaun White, the 28-year-old from the United States who is one of most successful snowboarders of all times with two Olympic gold medals and a record medallist at the X-Games.

White said: "I think this is the kind of future this event should go. This is something that I always wanted to do ever since the MTV sports and music festival when I was a kid and let's make it happen."
