Thumbs up on this one
Color: Khaki, Size: X-Large
Very nice soft material that seems like it will be easy to clean and pack without wrinkling. A bit heavier for cooler mornings and so nice it has pockets. Nice pullover.

Nice, but not as nice as I'd hoped and the shoulders are too tight
Color: A-black, Size: Large
This is nice, but not as nice as it looked in the pictures. Still very good value for the price. It's a medium-heavy weight Q-zip that looks good, but the pics online were much nicer looking. It's comfortable and warm, but just ok overall.
I like that the collar is on the taller side assuming I would wear it golfing in cooler weather, but the pockets are kind of shallow. It fits well overall, but the dealbreaker for me is that the shoulders are tight with a Large size. I could wear this out casually, but I don't think I could swing a golf club. I am 5'10" and "husky" in my old age and my shoulders are probably on the broader side, but the rest fits well so I was surprised how snug the shoulders were.
