I've worn out a couple of those old Columbia Shirt/Jac's in my time.
I'm older and wiser now, and really hate hunting in camo.
These days you'll see me wearing an Icebreaker Classic half zip in their old discontinued brown heather color.
Or an Ibex Scout Half Zip in an OD green color.
The new generation of technical merino wool clothing has a LOT going for us outdoorsman types. Especially the trad bowhunter... The thumbloops on the Icebreaker pull shirt sleeves nice and tight, out of the way of bowstrings. Plus, it's a great way to still keep the "feel" in your archery while keeping hands warm.
Both the half zip pullovers I mention are a 320 weight fabric. It's perfect for me early and late in the day during bow season in Montana. I dress warmer or colder by what I use for a base layer. Again, on base layers, I prefer merino wool. I either have on a 150 weight t shirt, or a 190 weight Ibex Indie Henley. I always have along a Patagonia Houdini wind shirt in my kit too. With that for a layering system on top, I'm good from 40 degrees up to 90, and can survive windstorms, and even rain until I can get to proper shelter. This same set-up works just fine in the winter, as long as I'm moving. I've snowshoed in this setup down to 10 degrees.
