Ultra Mix Blue by Holmenkol is a high quality coldest conditions ski and snowboard wax for when the temperature really drops on the mountain.
When the snow temperature tumbles below -8°C and towards -20°C this wax will perform.
Recommended iron temperature: 135-145°C
Snow temperature range: -8 to -20°C
Snow types: all snow types - especially effective on cold corn snow and old coarse snow
A much harder wax compound, it resists coarse snow crystals and hard abrasive snow that colder conditions bring, and retains its structure for longer as a result.
For best results use a brass/bronze brush alongside a nylon wax brush to really open the structure up and help improve glide performance.
With this wax set your iron to 140°C and ONLY use a ski waxing iron at this temperature as this is right on the limit of the maximum temperature you can use on bases without risk of delamination.
