Guru Blue Special is a softer blue with silver and tar additives for the best anti-icing properties on offer from a grip wax. For temperatures from -1°C to -8°C, it can be a big problem in humid, fresh snow conditions to find a wax that won`t ice up and give you grip at the same time. The wax has to be soft enough to get grip against the humid snowpack, and at the same time, the sharp new-snow crystals easily get stuck in a softer wax - causing a literal snowball effect of icing under your foot. The Silver and Tar additives smooth out the grip wax and repel moisture so snowballs are less likely to form. This wax is fantastic if the ski trails have varying levels of moisture from one spot to another.
