The Swix T157D is a horsehair brush specifically designed for skis and snowboards to achieve the ultimate racing finish. Unlike nylon or bronze brushes that excel at cleaning out the ski base structure or removing old wax, the super soft horsehair bristles gently polish the freshly applied racing wax for an unparalleled level of smoothness. This meticulous polishing minimizes friction between the ski base and snow, maximizing glide performance and allowing you to translate every ounce of your effort into forward momentum. Imagine the difference between running on a freshly paved road versus a gravel path – the Swix T157D aims to transform your snowy experience into the paved road equivalent, letting you ski with less drag and achieve those coveted personal bests.
