I bought the Dainese Air Crono 2 Jacket (Black/Glacier Grey/Black) in January and I really like it so far. As far as the fit goes I think it follows the trend of most European cuts and could fit a bit tight. I'm 6' 0", 175 lbs, and I ordered a size 50, which fits perfect on me. It feels light weight, movable, and I still feel protected with the shoulder and arm armor inside. It does not come with back or chest armor, but it does have sections for both if you want to add them. The integrated mesh makes it really breathable, which has been great for warm days, but if I throw a liner underneath it I've been comfortable riding around in 50F weather. THE ONE ISSUE I've had with this jacket has been the Velcro collar. On a few occasions the wind and my movement have undone the collar and my beard has been caught in it. If it had a button instead I think it would of gotten a perfect review on comfort. Still, It's a great jacket and I really can't pass on the price, I highly recommend it!

I love dainese. However I'm not sure this jacket is really up to their standards.
The jacket looks awesome. It's dainese. There is tons of mesh so it's going to be as cool as a jacket can be. That being said though there's some things that are making me question if I'll keep the jacket or not.

First thing that jumped out at me was the mesh on the back of the arms. I want as much airflow as possible on hot days but that mesh is way too close to the middle of the elbow. The seem basically runs down the middle of the back of the forearm and elbow. Next is the size of the forearms of the sleeves. Specifically the lower half. It's pretty large. I get that their armor is larger than most but I think they do too much to compensate for that and could tighten the sleeves a little which is not just this jacket I see that with almost all their jackets.
Next is the chest. Like another reviewer said it's rather large. Even with chest armor in it would be large. Another thing on the chest is the pockets for the chest armor is Velcro closures instead of the zippers on every other jacket which makes it feel bulky.
I really want to like the jacket however I don't know if I'll keep it. I was going to go with the super rider but I wanted to see if there was another option first that wasn't $500
So if you want a super light weight really cool looking jacket and you have larger forearms and chest this will work for you

Looking at the dainese size chart, I ordered a 50, I'm 5'8" 170lbs, 33" waist, 42" chest. It was way too long and bulky, so I exchnaged it for a 48. Kind of in-between a lot of their measurements, which should've been a red flag. Firstly, the fit in the sleeves is way too tight. So tight it is uncomfortable to reach into the (way too high) pockets. But the chest is loose and too long. There is no inside pocket, unless you count the two for chest armor. The jacket is too long in the chest for me and bunches up weirdly. I don't have this problem with any other jackets. The neck closure is scratchy and doesn't conform to a leaned over riders neck well.

On the positive side, the protection offered seems to be thought out well and fits where it should. I couldn't see this fitting anyone well, hence the overall 2 star rating. It is a bulky, scratchy, constricting, jacket.
