A ski winter sports device for sliding down a hill. The ski winter sports device includes a first ski, a second ski and a third ski, a standing device on which a user can stand, a holding device, and a frame. The first and second skis are arrangeable on the standing device next to each other in a direction of travel so that the first ski is available for a first foot of the user and the second ski is available for a second foot of the user. The holding device can be held by at least one hand of the user. The frame connects the standing device to the holding device. The frame is connected to the standing device in a relatively movable manner. The frame and the standing device are foldable relative to each other so that a spatial volume of the ski winter sports device is reducible.
