Great long sleeve jersey / jacket
I don't know the Gabba, but if it's anything like this jersey, I understand why it is so highly regarded.
I would recommend this jersey wholeheartedly. Not just because the colour is amazing.
The two negative things I noticed during my first rides with the jersey are the back pockets, that are different from the usual three pocket design, which means you have to come up with a new way of organizing your essentials. (Also there is a flap for the pockets, which is super nice for extremely harsh rain, but given that the material is "just" water repellent, seems excessive.) Second the articulated shoulders can become a problem for any rider that does not have the typical roadie physique. If you have a wider back or shoulders or muscular upper arms you can feel the seams around your shoulders. This feeling is less pronounced when you are in a riding position, which is a good thing. Overall a I'm very satisfied with the jersey.
