Next generation of Rex fluoro-free race glide wax, a step up from the G-Series. The RG-Line of waxes use a handful of new Rex technologies to speed up fluoro-free waxes such as UHW (increase of durability), N-Kinetic Level 2 (increased glide properties and dirt repellence, even more than G-Line), Power Polymers (works with UHW to increase durability), and 2-Step Carrier Solvents (allows application of these new advanced liquid waxes). RG42 is a very hard, wear-resistant wax for cold, crusty snow, coarse, wet snow, or icy conditions, between 5°C and -20°C. Great for long distances or alpine where wax resistancy is crucial. Comes in 150mL Spray bottle.
