Swix VR 50 Violet fluorinated Hardwax is designed for moist to dry snow around freezing 0°C (32°F). When used below freezing, high humidity is required. The VR Series Hardwaxes are characterized by a high degree of flexibility. Each VR-wax has two specified temperature ranges, one for falling and new fallen snow, characterized by sharp snow crystals with relatively strong penetration capacity, and one range for older snow, when the crystals are rounded off and have less penetration power.
