At first I really struggled with the zipper on this sweater.  It has two zippers; one zips up and one unzips from the bottom.  I still can't understand why someone would want such a feature.  It's pretty useless to me and I had a hard time getting the zippers to hold together to get them started the first time I put it on.  Then I discovered that there was a flap of fabric on the inside that was getting caught on the zipper's in-feed.  After I made that realization, I've not had much difficulty.  You do have to pay extra attention to keep both zippers together and aligned while keeping the aforementioned flap out of the feed, but it's not that troublesome once you're aware of it.

Another minor nitpick are the shoulder patches.  I'm not a fan.  I guess they would keep the rain from soaking right to your shoulder blades if you found yourself in a rainstorm, but they just look a bit silly.

The fit is good for me in a size small.  I have fairly narrow shoulders so sometimes it's hard to find things that sit proper.  This one does.  The one thing about the sizing that is a bit odd is the cut of the neck.  I guess it's done to be more fashionable, but the neck size is unusually small.  The neck corners come right up to mid jawbone on either side on me, leaving about a two inch gap from reaching each other under my chin.  I certainly won't be zipping it up all the way unless I'm more concerned about freezing to death than giving myself a mild case of hypoxia.  This doesn't bother me, but it might bother some.

Overall, it's a great sweater that's well worth the price.
