Great products. Fits me like a glove!
Jerseys are the best of the best! Such great quality and material feels great on your skin. I love the vented sleeves and look of them as well. Keeps you cool but also warm for those night time rides or early morning chilly days.
Size runs a little small due to it being a racer style fit so I'd suggest sizing up if you like your stuff a little looser not super racer style like myself.
I'm 5'7 about 180ish and wear an XL for reference!
I got the XS with the rustic plum color.
Pros:
I'm roughly 148lbs and this jersey has good stretch and feels nice even though its an XS. You are visible to all traffic. Even for low 40s F temperature morning commutes in San Francisco it keeps you warm. 
Cons:
Since almost having it and riding it on multiple  long weekend rides and short commutes only 1 thread on the right sleeve got loose, but that could be from the ride ID I have that rubs against it underneath.
Nit Pick:
The color is slightly darker than the images.
Verdict:
This is my go to jersey until it gets into the 70s.
