I bought the jacket because I was tired of freezing my butt off in the 35 degree Fahrenheit morning commute. After a few rides, the jacket definitely is not a cold weather jacket because it has a ton of ventilation through the mess chasis. This will be a great thing once it warms up this summer. The liner is designed for it's moisture wicking properties, and doesn't block the wind a lot, but I am no longer freezing during the morning commute. The jacket has a sporty fit - I'm wearing a large at 5' 11" 210lbs - it fits comfortably, and stops right at my pant line. And now for the cons - I gave the jacket 4 stars on comfort because the colar will rub my neck occasionally (if i'm racing my bike hard) and can be uncomfortable at times. Quality received a 4 star rating because the front zipper can be a little tricky when I get it zipped to chest level. It'll snag for a second, and then continue up. Also the interior liner sleeves do not attach to the end sleeves. (which is fine, but the sleeve liners tend to come out when I take the jacket off) All in all, I'm giving the jacket 5 stars because it's a tough little jacket, with C.E. Armor, massive ventilation, a good fit, and has some pretty great features (listed in the description of the jacket on the Dennis Kirk website) all for less then $200. I would buy it again.
