The Perfetto RoS 3 Jacket just might be the perfect jacket. One jacket to do it all. Windproof yet highly breathable. Essentially waterproof yet PFAS-free. Lightweight and with significant stretch for a perfect fit. It even looks premium. The magic comes from Castelli’s 15 years of development of the Perfetto (Italian for “perfect”) Jacket. The Perfetto RoS 3 represents the biggest jump since the original Gabba, thanks to the exclusive new Polartec® AirCore™ fabric with its PFAS-free semi-air-permeable membrane. In the search for constant improvement, the RoS 3 is more revolutionary than evolutionary. It’s significantly more breathable and water resistant than its predecessor. It also has more stretch than its predecessor, which allows for a close-to-body fit without feeling tight. It provides significant ventilation with zippered chest vents as well as a two-way zipper that you can open from the bottom. It is slightly thinner than its predecessor, for milder rides, but adding insulation layers can take you to very cold conditions. If your cool-weather riding includes showery days, this is the jacket for you.
