Turbo Wax is an exclusive formula designed for spring and summer skiing when the days get warmer and longer. Turbo wax is a rub-on ONLY wax that lasts about 10 runs per application. Why is this perfect? When you start in the morning the snow is firm and cold so you use turbo yellow. After about ten runs the snow loosens up and its time to apply another layer, but this time you apply the turbo orange. Finally in the afternoon when the snow gets real wet you use the turbo red.
