The R2v2 leggings are perhaps Compressport's most iconic product. These leggings take all the features that made R2v2 so revered: exclusive seamless multi-level compression, quick-drying fabric and a specially designed K-Protect knee eye for impact reduction, combined with even more revolutionary details. New Fibular Stripes activate proprioception to increase balance and stability, meaning fewer strains on the trail. Targeted horizontal knitting areas stimulate microcirculation and lymph flow, reducing calf inflammation. A reflective logo is added to the back of the leg for better visibility in the dark. After learning about a recent scientific report that showed that leggings can help reduce stomach problems after strenuous activity, Compressport has improved the knitting areas of these leggings to further promote blood flow throughout the body and reduce intestinal damage. In short, no more stomach cramping DNFs. Whether you're jogging around the park or halfway through the Barkley Marathons, the R2 3.0 will help you go the extra mile.
