Rex G21 Blue is a fluorine-free version of HF21 Blue, equipped with top-performance lubrication technology such as N-Kinetic(TM) nanoparticles, Power Polymers(TM) advanced wax blend, and 2-Step Carrier(TM) solvent technology. The glider is suitable for all snow types in temperatures from -12Adeg to -2AdegC. Here in a convenient bottle with sponge applicator for quick and easy application without spills. The N-Kinetic(TM) nanoparticles consist of hydrophobic polymers that give the glider extra performance on new, cold and fine-grained snow, as well as snow with relatively high humidity. Power Polymers(TM) is a new generation polymer-wax blend that creates a very strong bond with the UHMWPE base material used in racing skis, thus ensuring excellent durability. 2-Step Carrier(TM) is a solvent that enables the production of ultra-hard glides in liquid form. Temperatures: -12Adeg to -2AdegC Volume: 60ml
