The Perfetto RoS 3 W Jacket from Castelli is an advanced cycling jacket designed for a wide range of weather conditions, combining windproof properties with strong water repellency while offering good breathability. The innovative Polartec AirCore fabric provides a stretchy fit that moulds to the body without restricting freedom of movement. This jacket is the result of 15 years of continuous development and improvement, making it one of the best options for cyclists travelling in changeable weather conditions. With a thoughtful design that includes vents and a two-way zip, the Perfetto RoS 3 W Jacket is both functional and stylish. It works well for mild weather riding, but can also be combined with additional layers for colder conditions.
