If You Had Just One Women's Jacket
The Perfetto RoS is the one jacket that does everything well. Castelli initially designed it as a cool-weather training and extreme-weather race piece for their pro riders, but in reality it excels in many conditions thanks to its full wind protection, great fit through stretchy fabrics, and best-in-class breathability. The Perfetto family features are all there: excellent Women's fit, easy-sliding YKK zipper, long tail to protect from wheel spray, reflective panel on the back, and discreet styling that belies the jacket's racing pedigree.
It's also the ideal weight: no built-in insulation so you can layer over a light base layer for moderate conditions. Or you can add a thermal jersey underneath and take it to very cold conditions. You decide.
