Big air is a sports discipline where the competitor rides a vehicle, such as a motocross motorcycle, a skateboard, a snowboard, or a pair of skis, down a hill or ramp and performs tricks after launching off very large jumps. In most versions, there is one large jump and therefore only one opportunity to perform a trick. It is an extreme version of slopestyle. Competitors perform complex tricks in the air, aiming to attain sizable height and distance as well, all while securing a clean landing. Many competitions also require the rider to do a specific trick to win the major prize.
