    Exceptional protection, come rain or shine.

    A winter classic, the Castelli Alpha ROS Jersey Limited Edition holds its spot in your cold weather cycling wardrobe with vigor. Solving the problem of whether a jacket or jersey is ideal, the Alpha ROS Jersey lands its self as a hybrid between the two, with warmth and weather resistance, but without reaching an overpowering build that doesn't function well when the temperatures are shy of freezing. This jersey is unique for its double layer front construction that works to slice through wind and showers externally, while insulating internally. It features precisely sealed seams where it counts most, to keep nearly all water out while breathing.

    Featuring the same construction as the standard 2018 Alpha ROS Jersey, you can count on the Limited Edition model to perform exceptionally in cool weather days, whether sunny or full or showers, after all, Castelli's ROS stands for rain or shine. The ROS line is designed to cut through wet and windy conditions better than your typical jersey, and provide a bit more warmth than a rain shell on its own. Because not all of the seams are sealed, the jersey is perfect for misty and drizzly conditions, but may not stand up to serious downpours without leaving you damp underneath. With a similar design to the Alpha ROS Jacket, the Alpha ROS Jersey features Windstopper material, but is a little bit lighter weight, making it suitable for slightly warmer temperatures.

    In 2017 the Alpha ROS jersey saw some improvements that were carried on to this 2018 limited edition model, with new fabrics that increase water repellency, and minimization in seams to increase weather resistance in dreary weather. The zipper was also elevated to a waterproof design, keeping you sealed in, and laser cut drain-holes on the rear pockets keeps water from sitting and penetrating into the jersey. On the back you'll find Nano Flex Xtra Dry that offers incredibly water protection while maintaining breathability, so you can keep all unwanted moisture out. You might be wondering what makes the limited edition model different; this model features the same construction as before, but in an eye catching red hue that stands out with its bold and rich color in a sea of black and fluorescent yellow.
