Purchased a Venturi II a couple of months ago and have used it in a variety of conditions. Generally speaking I like it quite a bit!
It is pretty warm (in condtions right around 0C / 32F I was using just a single marino wool long sleeve jersey underneath it and fine) I've used it up to about 10C so far, with a fair bit of success. You have a lot of options with the venting in the jacket.
Had it in one major downpour with hail, for about an hour ride, and it held up fine, some of my jersey was damp from sweat (but not bad at all really) and the rest of it was dry!
Definitely more breathable than my old stuff, and much better at keeping a comfy temperature.
