Sit-skis are used for para-Nordic skiing and para-alpine skiing.[2][3] If the sit-ski has one ski, it is sometimes name a mono-ski. If a sit-ski has two skis, it is sometimes called a bi-ski.[3][4] Skiers first used bi-skis in para-alpine skiing before using mono-skis. Mono-skis allow skiers to ski using the same way that people who stand ski down a hill.[4]
Sit-ski users use outrigger skis.[2] In para-Nordic skiing, a sit-skier may use a normal ski pole that is not as long as one people standing up to ski would use.[5]
When skiers first learn to ski, their teacher may be connected to them on a tether until the skier can control the sit-ski on their own.[2]
