Mogul skiers use stiff straight cut skis that are between 165 and 190 cm. in length. Mogul poles are shorter than those used on flat terrain. Shorter poles allow the athlete to plant their poles on the top of moguls without a lot of exaggerated movement.
Aerial skis are shorter (generally 160 cm. to allow more manoeuvrability. Poles are either used or not depending on the trick the athletes chooses to do. Some athletes choose to go off the jump (and land…yes land!) backwards. These athletes and those in the Half Pipe use twin tip skis (or twinnies) to facilitate this.
Helmets are mandatory in all disciplines mouth guards which protect teeth and prevent concussion are strongly recommended.
During the summer that athletes train on trampolines and water ramps (artificial ski hills and jumps with plastic running surface and a water landing) to perfect their tricks in a safe and controlled environment.
