Cycling Weekly Verdict

The jacket has an excellent balance of waterproofing and breathability. There's no clammy boil-in-a-bag sensation when pushing hard, yet it still kept me toasty and warm through some pretty unpleasant conditions. Of course, there are limits: you'll want a proper hardshell for extended endurance rides through the heavier and sustained rainfall, and it'll need a base layer for when the temperatures get properly frigid – but all that still leaves a huge window where this jacket is just the ticket.

The story goes that the Castelli Perfetto long sleeve gained its name because so many people kept calling the Gabba, its predecessor, 'perfect'. Now, this might sound like the Castelli marketing machine in action, but through all my rides testing this jacket, I have been very impressed. 

The Castelli Perfetto ROS long sleeve jacket comes in a range of different colourways with a variety of far-out patterned designs. The one on test here is the simple navy and red option, but you can look through the others on Castelli's website.
