The ASSOS R Winter Knee Warmers provide the warmth and protection necessary to ride through the rainy, cold seasons. The RX Extreme textile, a brushed, thermoregulating warp-knit fabric with optimal breathability and water-repellency, keeps our knee area dry and warm as we ride through changing conditions. The AEPD 11 racingFit doesn't interfere with our aerodynamic setup and the lie-flat, low-volume cuffs eliminate friction and stay in place with the microdot silicone treatment across the leg opening.
