Classic casual!
What fiber material is ideal for you?
ETA, because I couldn't help looking up versions with buttons:

None of these have exactly what I think you're describing, but some have lines you might find interesting.
It looks like this is the original source of the charcoal hooded, zipped, long sweater I bought used online last year, and loved through a damp winter. If it's merino as labeled, it's not the long fine kind; it's scratchy. I'm the most scratch-averse person I know (can't wear cashmere) but this works because I don't wear it against skin. Charcoal-heather turtlenecks made it my woodsy casual, cosy "twinset." The length isn't the most flattering on me, but the two-way zipper allows for some visual vertical adjustment.
