Hey guys!
So, ive been following this and picked up a few patterns to take a stab. One is the Fairbanks Anorak (
https://www.thegreenpepper.com/product/124-mens-fairbanks-pullover-pattern/). A few small mods to this and it will be right on, I think, but a one use item, and expensive.
So...hear me out here...what about a saddle hunters poncho? A poncho is multi use, much cheaper, and easily packed? You can also rig it shield hanging gear from the rain, while wearing. It will provide the rain and wind protection, but you would have to pack or wear a mid layer.
I would take something like the below linked pattern, use a fairly light weight wind/water resistant material, reinforce the chest pocket, add a fleece lined pass through pocket as well as diagonal slots with snaps so that it could be passed through and around a bridge.
