Start's new line of fluorinated racing kick waxes.  You can use them on their own or apply them as a finishing layer over other layers of kick wax.  These fluoro waxes give good grip while reducing the friction between the wax and the snow, therefore allowing better glide than non-flouro waxes. 

Temperature range:  3° to 1°C (37° to 34°F)
Snow type:  variable, works best in humid conditions
Application: apply a thin layer and cork in; repeat 2 or 3 times (the more layers you apply, the longer the wax will last)
