Overall I have been happy with this jacket. It packs down pretty small. It's nice for summer use as it breaths well and doesn't have any added insulation. I haven't had any issues with the rain protection. The zippers are all rubberized to protect them from rain as well.
I ordered the jacket in my usual size. It generally fit as expected with slightly longer sleeves than normal. However, with properly adjusted velcro wrist closures the long sleeves aren't a problem. The hood is a bit oversized which can be a positive or negative depending on your intended use. Even without any kind of hat or helment underneath, it's not so large that's it's a problem though.
The velco wrist closures are my biggest complaint. They come undone very easily. I'm a little confused by the design choice to use half regular velco but for the other side a piece with large rubber teeth. The rubber teeth simply don't grab onto the other velcro side well at all. While it rarely completely seperates, it always stays loose and you constantly have to check it.
All in all for the reduced price I got this jacket for, it has been a great purchase.
