The "triski" is a snow board made from flexible plastic which has two handles, two small cords and a groove 1. This board has a head in the form of a tip. There is a groove 1 on the lower face. Owing to its depth, this groove limits the digging-in of the two inclined lateral planes 2 and 3. This inclination increases grip on slopes. Sliding is effected by a person holding the handles and displacing his centre of gravity from side to side in order thus to produce diverse movements. <IMAGE>
