Great jacket, not waterproof.
This is great as a windbreaker or shell. I've worn it by itself and layered up with fleece underneath. It does the job and the pockets and pit zips are great. Usual high MH build quality. It is NOT a rain coat, though.
You could take this out in a short duration light rain but don't pack it as your go-to shell in case the rain dumps while you are hiking. The outer fabric will get saturated and then start to seep inside. You will get cold and wet.
If you know it's limits, you'll have a great time in this light piece of gear!
