Building on the legacy of the Gabba, the Castelli Perfetto RoS Jacket brings race-fit weather protection perfect for racing, fast riding and high-intensity training throughout the cooler months and winter. Castelli uses GORE-TEX INFINIUM fabrics in the Perfetto to offer protection and breathability where you need it most. The front of the jacket has a windproof and water-resistant fabric with a brushed interior to protect your core, whilst the back of the jacket has a stretch and breathable fabric for freedom of movement and to help any moisture escape. The rear of the Perfetto has two pockets. The wide design of the pockets makes it super easy to grab any nutrition or supplies even with gloves on. There is also an integrated pump sleeve in the pockets. The front of the jacket has two zippered openings for quick and easy ventilation on the fly. A drop tail provides some welcome extra coverage on wet days, and a large reflective panel will help you stay seen even in low light. The jacket closes with a YKK Vislon zipper.
