Compressport was born in Switzerland, a country that favours sport and innovation. With this in mind, the Pro R2 Swiss was 100% designed, developed and produced in Switzerland. We wanted to bring a racing specific product to take our elite athletes performance to the next level.. The Compressport Pro Racing Calf R2 Swiss calf guard boosts your venous return, reducing the accumulation of toxins while increasing oxygenation to the muscles. With Scientifically proven performances, exclusive technologies, tested and approved by the best pro athletes in the world, the PRO R2 Swiss will take you to the next mile. Lighter, the PRO R2 SWISS weighs 11 g when dry, does not retain water when wet (no sponge effect) and dries quickly. With his new Bio-ceramic crystals, actives the microcirculation on the surface of the skin (+92%*) that benefits from this bio-stimulation and better thermoregulation.
