Familiarity: I've used it several times
Living in MN, I wanted something to get me deeper in the cold. I've had the Gabba LS (now called Perfetto) for a couple years, but getting enough layers on underneath gets uncomfortable due to the Gabba's aero fit. The Espresso is heavier with its own insulation and less tight fit making layering much more comfortable.
Thus far I've taken it out in 25°F with a couple baselayers and had no complaints about the cold. I'm not a big guy and some of my mates say I'm "made of air". I'm always the first one to bring out the long sleeves and the last trade for short sleeves.
The outer fabric does exactly what is says. Block wind and repels light water (think sprinkles, light snow, road spray). Caught in the rain, this is not quite the right tool.
Fit is great, warmth is great, feels great.
