This convertible Castelli Perfetto is a lightweight jacket perfect for riding & racing in cooler, changeable conditions. With a removable zipped sleeve, this jacket allows for an incredible amount of temperature regulation on the go. Thankfully, the zips are completely covered both inside & out, meaning they can’t be seen or felt. Constructed with Gore-Tex, & forming part of Castelli’s rain or shine collection, or Ro S for short – this jacket provides an equal amount of protection against both cold & wet conditions. As such, while the front of the jacket is constructed with a slightly heavier fabric for wind resistance, the rear panel is made with a slightly lighter fabric for better breathability & water repellence. Castelli has completed this jacket with reflective detailing for heightened visibility, a durable YKK zip & a long tail for increased protection against wheel-spray.
