This is the first real bike jersey I've owned and I LOVE it!! I grabbed it off Chainlove for 15 bucks and am soo happy with the purchase. It can get a little muggy in the woods here in SW Michigan in the summer, but this shirt really helps keep me cool. I'm about 6' 175lbs and the medium fits me like a glove: not tight, but nicely fitted. I just discovered a neat feature the other day; there is a grommet sown on the inside of the pocket on the back for passing a headphone cable through. Will definitely have to take advantage of that!
In all, I have just one regret...I didn't get three of them!!
