I tested this on my first real ride -- 70 miles. The jersey keep me cool during the heat (upper 80s) and the front zip came down easy on the ride for extra ventilation. The pockets are awesome, especially the hidden pocket, which is zipper so you don't have to worry about losing the important stuff. It also looks great and the red is a really nice color.
My one complaint is the front zipper is really uncomfortable below the halfway point (between the sports bra and belly button). I have another jersey that's a 3/4 zip that is not bothersome, so I don't think it's just the length. I itch while note on the bike, thought I didn't really notice it on the ride. But, for the money, I expect comfort in both places. This is going back. If not for this, I would have rated the jersey 5 stars.
