Rockislandwrote a review of Gore Bike Wear Countdown GT Jacket on May 17, 2013
This jacket is absolutely not a slim fit. I have another Gore Jacket which is comfort fit same size. It is a lot slimmer than this jacket. This is more than acceptable relax fit for biking or running.
The outer shell material feels very cheap. You can feel the same cheap quality on any $20 sports jacket.
I am not sure whether the shell material will be able to hold the water for the gore-tex to be able to breathe.
Disappointed on Gore's quality control. I have another jacket which is very good quality and another pants which is good too.
I am 5-6 130lb. I ordered size S.
