The Compressport R2 3.0 Calf Sleeves are a revolutionary compression-wear product, designed for comfort and support during physical activity. The R2 3.0 version builds on the classic R2v2 design, featuring exclusive seamless multi-gradual compression, quick-drying fabric, and a purposely designed K-Protect knee tab. The new Fibular Stripes activate proprioception for increased balance and stability, while targeted horizontal waffle knit areas promote microcirculation and lymphatic flow, reducing shin splints & inflammation. The sleeves also feature a reflective logo for heightened visibility during nighttime activities. Recent scientific reports show that the sleeves can help reduce stomach problems after strenuous activity. With the R2 3.0, whether you're jogging or participating in an intense marathon, you'll receive the support you need to go the extra mile.
