I have Vias, brown and olive, and I like all three. I agree with almost all of the comments here. Hoods are funny things -- when you want them, they are great, when you don't want them, they get in the way (or flap in the wind, or ...). The Guide wear is not designed to be particularly warm, which is why you will need some insulating layering, like Primaloft or down, both of which Kuiu sells and recommends. Other products are probably better in really cold weather on a treestand, where I tend to get VERY cold when the wind is blowing and I'm unable to move around.
