Perfetto RoS Vest
A primed engine pushes through the most miles, and optimizes energy and fuel for total efficiency climbing up mountain passes, and soaring across wind-swept straightaways. In cycling, our core resembles an engine, and our finely-tuned machine will only truly show us what its capable of if that engine is taken care of. On cooler morning starts, we suggest that the best way to do this is with the Castelli Perfetto RoS Vest. The Perfetto RoS takes the fit and form of the coveted Perfetto Vest and brings it further into the future with elevated fabrics that provide more protection than its previous iteration, thanks to GORE's latest and greatest textiles at the front, and Castelli's fan-favorite Nano Flex Light.
The Perfetto RoS differs from the standard Perfetto in its front panels that are built from Gore's Infinium 203 Stretch lightweight fabric, as opposed to the Windstopper X-Lite previously used. The new Infinium 203 provides more stretch than Windstopper could provide, while still maintaining windproof protection, and minimal weight, enabling you to cut through icy winds, while still allowing skin to breathe and drop heat when you're pushing yourself up major elevations and steep pitches.
We appreciate the saying "if it ain't broke', don't fix it," and even more so, we're thankful that Castelli stuck with a good thing by keeping its Nano Flex Light fabric at the back panel. Nano Flex Light is a flexible, thermally insulating material that's been coated with countless nanofilaments in order to add water-resistance. It gives flex across your shoulders and ventilates better than the vest's front, helping to regulate your body temperature for rides where the full Perfetto would be too warm and addressing a wider range of conditions with additional layering versatility.
Like the previous Perfetto, the Perfetto RoS Vest is packable, so you can use it for chilly descents without overheating on the climb. Castelli recommends it in temperatures ranging from 57 to 68 degrees Fahrenheit, but the layering possibilities are only limited by our daydream imaginations, so this number can drop easily into the 30s. (And no, we're not embarrassed to admit that we waste time at our desks daydreaming about layering. Well, not that embarrassed.) The full-length YKK Vislon zip boasts a wind guard across the entirety of its span, and the tall collar extends the Infinium 203 to cover your neck. Reflective elements at the sleeve holes and hem help keep you visible in low-light conditions.
