Cycling Protection. Come Rain or Shine. After four generations of the Perfetto long sleeve, the Perfetto ROS Long Sleeve Jersey gets the biggest performance upgrade yet, as denoted by the ROS in the title, Rain or Shine. This cycling jersey delivers comfort across a remarkably wide range of winter cycling conditions. Cold-weather comfort is taken care of by two exclusive Castelli GORE-TEX INFINIUM™ fabrics by Gore, a lightly fleeced front panel keeps in warmth while a lighter and high stretch rear fabric enhances breathability, so you always feel at just the right temperature. However, should you get caught in rain or snow it's then that the water repellent performance of the INFINIUM™ fabrics really come into their own. The Perfetto ROS is also the perfect weight for layering - use a light base-layer for milder conditions or add a thermal jersey underneath for more extreme cold. You decide. Details Honed With improvements to the fabrics complete, attention was then focused on getting all the details right. Improvements can also be found to the pockets, now larger to accommodate gloved hands, so no more frustrating fumbling for that energy gel. They also feature a pump sleeve inside, while below the pockets a dropped tail adds extra rear wheel spray coverage. Easily accessible side zipped vents boost airflow and a large reflective detail on the back is ideal for those shorter, darker days of winter. All details that really count towards comfort when cycling in the cold and wet. If there is just one item of clothing to see you cycling through autumn, winter and into spring, then the Perfetto ROS Long Sleeve Jersey could be it. An investment in your comfort as you tap out those colder weather miles in anticipation of summer smiles.
