I got this jacket to go with the Beretta bibs, and so far, the setup has been great. This jacket is solid- the 3L gore keeps you dry all day, and safe from the winds. It has a good cut to it as well- it is more feminine, not super baggy, but also not skin tight. The vents are really nice- while they're not directly under your arms, they're still great at getting airflow in, and honestly, it's easier to tell if they're open or closed... The internal mesh pockets are great too for stashing stuff temporarily. if I were to be picky, there are a couple of updates I'd like to see- first, the zippers can be a little annoying, they do really like to get hung up on the flap underneath, it would be nice if they were just a little more smooth. Second, the flaps on the hand pockets are annoying if you're cruising at speeds as they flap around. And last, it would be really nice if there was an internal zip pocket. As it is, there isn't really a good place for your phone- I store mine in the bibs chest pocket so it doesn't freeze.
As far as sizing, I feel like the jacket itself runs pretty true to size. I sized up intentionally to get a little extra room- I'm 5'2, 120lb, and I have the Medium. On its face, it fits fairly similar to my old Burton AK Medium jacket. However, I find the powder skirt to run rather tight. Even on the "loose" setting, it's small. While it certainly fits, I find that the tightness causes it to ride up a little more, so you're having to pull it down.
All in all, while there are a couple of minor things that I would improve if I had the chance, I still really love the Beretta line and would definitely recommend!
