The Swix CH6/CH6X is another variant that remains the same from the old Cera Nova system. Similar to the LF7X, comprehensive testing has left Swix unable to find anything better, so the formula remains the same. CH6X stands out as an economic training and racing wax, as well as a base prep wax for cold skis. With high durability, CH6X offers great performance in most snow conditions including artificial and glacier. The 'Fluor Free' badge on the label signifies Swix's commitment to environmentally friendly and biodegradable products. The company is continuously working on being able to offer fluor free alternatives in each of their wax categories to minimise their impact on the environment.
