For cold and firm conditions between 10°F and 21°F, the Swix TS6 Black 40G Wax provides exceptional glide when natural snow turns contaminated or is reshaped. Enhanced hardness boosts durability and repels dirt, while the solid lubricant additive slashes friction on gritty or artificial surfaces, keeping you fast when others slow down. From early-morning training to race day in challenging snow, this wax gives you the grip-free speed and versatility you need to stay competitive.
