Jon Twrote a review of Castelli Perfetto Vest - Men's on December 21, 2018
Familiarity: I've used it several times
This vest has reached near perfection levels. The addition of the two rear pockets is simply brilliant and they hold plenty but lay flat when not in use. The gore fabric stretches beautifully, blocks the wind and light moisture, and the back breaths incredibly well. No fabric flap but you can still expand your chest in it when breathing hard. Zipper slides very easily for quick heat dumps. And I did I say that it simply looks amazing? This is a race fit so be ready for a close to body fit everywhere, including the arm holes. If you want a relaxed fit, size up one or look for a different vest. Once on the bike you forget it is there. Have been riding this in temps from the low 40's to about 60 with NanoFlex arm warmers and couldn't be happier. Zip down for the hills and zip up for the descents. I'm a large in Castelli and found this to be true to size though tighter due to the race fit. My new favorite piece of kit for Nor Cal winters.
