The SKY Pro jersey is very much like the Pro Team jersey in fit, it may differ slightly in materials used, and it won't have a zipped pocket like the Pro Team does. SeƱor_Bear will give you a better answer than me though.
One thing I have noticed is that this years Pro Team jersey is different to previous versions, it seems to have more pocket space at the back. So, I would guess that the SKY jersey is more like the previous version of the Pro Team jersey?
