I don't mean to be picky or debate the topic but for me a zipper is the only way to go. If its a little chilly one morning early season, then starts to warm up, all you gotta do is un-zip and slide it off. With a pull over, you are gonna have to make all kinds of movement to take it off when you are burning up.
Also with a pull over, if I wear it out to eat, or wherever, when its 50 degrees outside, then walk into a restaurant thats 75 degrees, I have to stand up at the table, and pull it over my head to be shed of it and get myself back to a comfortable temp.
I like pull overs and have all kinds of them. But I really only wear them hunting or to work when its cold, as an under layer. As far as being wearable and versatile, give me a zip up any day.
I'd rather have a couple of these to show off
Thanks Terry for thinking about trying for a zip up. Like I said earlier, I'm in for two of 'em either way.
