Castelli Perfetto RoS Convertible Jacket Review
As with many other winter clothing, there is a trade-off between breathability and protection. Usually, breathability comes as a cost to the level of protection against the elements, and vice versa.
Castelli uses the latest Gore-Tex fabrics called in the Infinium for the Perfetto. Gore-Tex Infinium was launched back in 2018 with a focus on comfort and performance. Unlike the original Gore-Tex, which is 100% waterproof, the Infinium trades off waterproofing capabilities for increased comfort. The Windstopper technology is also built into the fabric, making it 100% windproof.
Hence, the Castelli Perfetto is not 100% waterproof, but water-resistant to a high degree.
To further improve the breathability and hence comfort, Castelli uses two different Infinium fabrics for the front and back panels.
- Gore-Tex Infinium 205. The front is where protection takes precedence over breathability. The 205 is a slightly heavier material that offers more protection.
- Gore-Tex Infinium 203. The rear is where breathability takes precedence over protection. The 203 is a lighter material, making it more breathable at the slight expense of protection.
From my experience, I’ve stayed comfortable (dry inside) most of the time except when I’m riding hard up a climb. If you’re just cruising along or riding tempo, you’ll be surprised how comfortable the Castelli Perfetto is.
