This is a very comfortable "fleece" (interior, not exterior) with decent wind-resistance that I've been wearing daily since I purchased it sometime in December 2011.
There are a few minor areas which made me mark this as 4/5.
1. As previously mentioned by others, the seams fray as the zipper handles get caught on them. I've had to trim them several times. It seems a bit of a design flaw.
2. I'm 5'10" 170lbs with 39" chest (an average athletic build) and the sizing was an issue for me. The Medium (size I wear in everything) was tight all around and I didn't really like how it fit. It was almost like a Medium-minus. I exchanged it for a Large which is more like a Medium-plus and fits great except for the long sleeves, which is to be expected given the size-up.
This is a great buy when it's on sale. :)
