Frankly, that's probably what I'd get if it was a button down (non-negotiable for me). I did find Poncho Outdoors which seems like it's going to be good enough, still have to give them a good test. Don't care much for the magnetic pocket flaps or the big branding tag on the pocket, but everything else is about right. I'll see how they work after wearing for a few weeks.I have a couple REI Sahara short sleeve shirts. They also make long sleeve ones. https://www.rei.com/product/193091/rei-co-op-sahara-solid-long-sleeve-shirt-mens
They are nice looking and easy to take care of.
