Castelli Perfetto RoS 2 Convertible Jacket Increasing versatility thanks to removable sleeves, the Castelli Perfetto RoS 2 Convertible Jacket works well in foul conditions, be it mild or freezing cold. Just like the Perfetto RoS 2 Jacket, this garment offers full wind protection, is waterproof on front-facing surfaces and is highly breathable. Through layering up, you can make good use of this item through autumn, winter and spring. Additional details have been added to maximise protection from the elements. The shoulder seams are taped and the two-way zip is covered. The sleeves unzip just above the elbows, so can be removed at any time and stowed in a pocket, creating a short-sleeved jacket, and there's also a zipped opening on the chest for additional ventilation when required. Reflective details are incorporated into the design, in a panel at the bottom of the pockets, enhancing visibility in low light conditions.
