This Swix category has no fluorocarbon material in the blends. They are 100% high performance hydrocarbon paraffins. Although they can be looked upon as an economical racing wax group, the colder waxes perform very well alone, and the warmer waxes make an acceptable base layer for Cera F. Their colors and temperature ranges coincide with the HFX and LFX Waxes. The CHX waxes can be distinguished from the LFX waxes by their darker shade of color. It is an economic training and racing wax as well as a base prep wax for cold skis.
