I love this jacket. For the price, I paid, this was a great deal. In fact, Revzilla even matched the price that I had found elsewhere.
Size wise, I am 5'9", weigh 175lb have a chest of 42 and a waist of 34 with a gut of about 35/36. I bought the large size and its a perfect fit. They said that these tend to run a bit large but I found them true to size.
I love the part where the collar style is a bit open and does not choke you. The shoulder pads tend to move out of place and you have to manually push them back in place when you put the jacket on (not a major issue). The liner is great and keeps you warm. The jacket could use a bit more pockets on the inside.
The only major negative on this jacket is the venting. There are no vent zippers in the back. So, even if you have vent zippers in the front, there is no place for that air to go. You really need to have vent zippers in the back to pull that air through creating that air flow. You are not going to enjoy this jacket in the hot summers but other than that, I don't think, I found any issues.
