Perfetto RoS 3 Jacket, probably the perfect jacket. A jacket for all seasons. Windproof but also extremely breathable. Essentially waterproof but without PFAS. Lightweight and with good elasticity for a perfect fit. And it’s even of the highest quality. Is it magic? No, it’s the result of 15 years of evolution of the Perfetto Jacket Castelli. Perfetto RoS 3 is the most innovative jacket ever made starting from the original Gabba, thanks to the new exclusive Polartec® AirCore™ fabric equipped with a semi-air-permeable membrane without PFAS. RoS 3 is the result of continuous improvements: not just evolution, but a true revolution. It is significantly more breathable and waterproof than the previous model. Also, it is more elasticized, allowing a close fit without tightness. It allows excellent ventilation, thanks to the zip openings on the chest and the two bi-directional zips with bottom opening. The fabric is slightly thinner than the previous version, for milder days, but with the addition of insulating layers it is also ideal in very cold conditions. And it is perfect, not only on cooler days but also in case of downpours. If instead you are looking for protection or a shell for rainy days, take a look at the Perfetto Air Jacket, even more breathable.
