New fallen snow 0°C to +2°C (32°F to 36°F). Old fine grained snow 0°C to -4°C (32°F to 25°F). VX63 is a top layer kick wax with high fluor content. Extraordinary properties when tricky conditions around zero. Also brilliant on the cold side when high humidity and older/transformed snow. The black ingredient speaks for versatility and great anti-icing properties.
