Polartec AirCore Castelli Perfetto RoS 3 Jacket ($320)
John: Whereas the Castelli Perfetto has lengthy been a staple on this planet of biking, I’ve at all times seen it by means of the lens of a cold-weather cardio fanatic. As a each day bike commuter and runner, I want a jacket that may deal with the trials of onerous efforts in chilly, and even damp, situations. This newest iteration, the Perfetto RoS 3, represents a major shift in philosophy, prioritizing breathability over absolute waterproofness.
My testing passed off by means of a basic shoulder season, with cool mornings, and a few surprisingly chilly days.
The match of the Perfetto RoS 3 is superb – a pleasant, aerodynamic minimize that also permits for snug motion because of the Lycra-like really feel of the brand new Polartec® AirCore™ cloth.
I’m normally small in attire, however Castelli typically runs smaller so I opted for the medium. This new materials is extremely intelligent, designed to be extremely breathable whereas nonetheless providing a practical stage of water resistance.

To really make this jacket work in quite a lot of winter situations, you should be strategic together with your layering.

When layered appropriately with a top quality base layer and a hardshell for heavy rain, the Perfetto RoS 3 will be a part of a really efficient system that retains you drier general.
