Swix's VP waxes are flourocarbon free and made for racing, although their excellent glide and grip properties make them fun for training as well. Each wax has two temperature ranges, one for new fallen snow with sharp penetrating snow crystals, and one for transformed older snow with more rounded crystals.
VP50 purple wax is designed for conditions a few degrees below the freezing point unless the tracks are glazed, in which case you may need a stickier (warmer) wax.
New snow temperature range: -0/-3°C
Old snow temperature range:-1/-6°C and colder
