The power of the Race-Series Thermal Jersey lies within its versatility. We all know that cold-weather riding can be a delicate edge to balance on, as we seek warmth but inevitably heat up as we ride. Thankfully, Polartec's Power Grid fleece knows how to navigate both worlds, trapping warmth while breathing well during intensive training. Its hydrophilic lining wicks sweat from your skin, while the face fabric disperses that moisture for fast evaporation—the last thing we want is to work up a sweat only to ride with frozen clothing.
