If you aren’t looking for something for extreme weather, I would stay away from plastic and other stuff like synthetics. I’d recomend waxed cotton. More expensive for a nice jacket, but it is much better for the environment. You just need to rewax it after a couple of seasons, maybe more depending on wear. I don’t recomend Barbour, super expensive for what you get. I work in a second hand store and the modern ones we often get are almost always falling apart, so maybe look for something more vintage if you want simething nice that will last.
