This jacket was just what I was looking for. It's light but windproof/warm enough, breathes well and is cut correctly (not bulky, arms are long enough so they're just right). The zipper was a bit cranky when I first got it last month and that had me worried, but now it's super smooth.
The only thing that could be improved are the rubber velcro cuffs. The velcro seems to be intentionally weak (probably so that everything your wrists get near don't get stuck to them and they can be undone with gloves), but that means they also undo themselves sometimes. Don't get me wrong, they're much better than elastic cuffs, but hopefully, the design team will get the hooks on the rubber side just a bit grippier on the next re-design. (Worse case scenario, if they really bother you, you could take a sharp knife and shave off the rubber hooks and put a strip of real velcro on them, just as long as you can glue it/sew it to the rubber).
For a top-end jacket, pit zips should also be added. Since I only paid about $90 for it, I'm more than happy with what I got for my money.
