Seems to work as designed
I bought this jersey on a bonktown clearance just prior to my first attempt at triathlon. I wore it in a sprint distance and olympic distance. I felt the jersey worked as advertised.
I never noticed the jersey during the swim, but I use a full wet suit. I was able to carry a pill pouch and some gel packets in the two rear pockets during the bike and run. The angled pockets definitely help getting in/out at speed, but it was still some finger gymnastics when I was getting fatigued.
The back panel definitely breathed well and relieved heat well. I was also grateful for the long zipper during the olympic event that was over 90 degrees.
I am 6'1" and 150 lbs. with a long torso to match, and I ordered a size medium. The front came down just below my belly button and just touched the top of my tri-shorts.
My one complaint was that it constantly rode up on me during the run, so I had to keep pulling it down. I have since bought another Voler two-piece kit, and it does the same, so I think I just need to move to a one-piece suit.
