The Compressport R2 3.0. To build on the classic R2v2, we took all the features that made the R2v2 so well-respected: like its exclusive seamless multi-gradual compression, the quick-drying fabric and the purposely designed K-Protect knee tab designed to reduce shock and combined them with even more revolutionary details. The new Fibular Stripes activate proprioception to increase balance and stability, meaning less sprains out on the trail. Whilst targeted horizontal waffle knit areas promote microcirculation and lymphatic flow, reducing shin splints & inflammation. And for when the sun goes down, we added a reflective logo to the back of the sleeve for heightened visibility. After learning of a recent scientific report which showed that compression sleeves can help reduce stomach problems after strenuous activity, we honed these waffle knit zones to further promote blood flow around the body and reduce intestinal damage. In short, no more stomach-cramp-induced DNFs. Whether you’re jogging around the park or you’re halfway through the Barkley Marathons, the R2 3.0 will support you in going the extra mile.
