My 10-year-old Campy full fingered gloves started coming apart this winter so I looked for something similar. I like Castelli's CDS pad layout (I have a couple pair of their Corsa Rossa gloves) so the Perfetto looked promising. I've worn them on every ride except one unusually warm day since Christmas. Every Castelli apparel I have is sized large (I'm 5'9, 160 pounds) where in US companies (e.g., PI, Hincapie) I take a medium. On one hand, I'm looking forward to a warmer Spring where I can shed a layer and get back to half-finger gloves. On the other hand, the Perfetto's are great. I hope they last as long as my old Campy's.
I am almost 62 and weigh right at 150 pounds. I like the way the medium fits me (not a lot of loose material in body or arms). I use it when I have been out and find that I need a jacket. It fits neatly inside of my jerseys back pocket.
