Abstract
Abstract A generally rectangular apron of flexible material has pocket means at its forward end into which the toes of the skis of a snowmobile are adapted to be inserted. The length of the apron is substantially that of the skis and its width substantially larger than the distance from the outside edge of one ski to the outside edge of the other, the side edges of the apron being provided with eyelets so that, when the edges are turned up over the top of the ski edges and a flexible cord progressively laced across from one edge to the other through the eyelets, the apron is securely secured to the skis and provides lift from the snow between the skis.
