With this jacket, you can ride fast on the coldest days or look sharp in cooler weather. At the heart of this jacket's design is our double-layer Alpha construction, ensuring you're ready for the start of the season. The stretch fabric allows for excellent airflow, preventing excessive sweating during exertion, because in winter, wetness makes you feel the cold. The second layer of Polartec® Alpha insulation provides exceptional breathability. It's also so lightweight that the jacket remains incredibly comfortable. The back panel is made from our Nano Flex Extra Dry fabric, which offers a good level of insulation without a membrane, allowing perspiration to evaporate easily. This jacket features a tailored fit to ensure the fabric doesn't restrict your movement, along with thoughtful details that make a difference, such as smooth-gliding YKK® zippers, reflective drainage holes on the pockets, and a flat silicone gripper at the waist. With its tailored fit, this jacket is also our most aerodynamic model. Not that aerodynamics is crucial in winter, but we firmly believe that speed is always a pleasure!
