Start HF80 Green is Start's High Fluoro version of the famous start green. Works in cold, high humidity snow or when the snowpack is extremely cold but sun-drenched. -7C to -25C (20F to -13F) range.
We used this wax extensively at the Canmore World Cup in 2008 and this is a favorite high-altitude Rocky Mountain wax for those cold nights followed by sunny days.
