Ski grip

But it also prevents you from going down very well either, because with all the dimples in the bottom of the ski, it doesn't make a smooth surface, and the ski doesn't glide very long. That's one solution. The other solution has been to put on what they call bear skins, and that's a long, thin skin of some animal fur that hooks on the front tip of the ski and wraps all the way along underneath the ski to the very back clips on the back
