Summer Slush from the F1 series is an all temperature graphite alpine wax that includes a liquid silicon additive making it an absolute awesome snowboard/ski wax for spring and summer conditions. Old, aggressive snow conditions that range from icy to slushy are ideal for this wax. Use as a hot wax but it can be used as a rub-on wax. Wax, cork, scrape, brush.
Optimal Snow Temperature: 32ºF to 28ºF (0ºC to -2ºC)
