I really like this vest and have been wearing it a ton with a sweater or just a long sleeved tee underneath (depending on the temperature). It is a quilted, synthetic fill vest with two outer pockets. It isn't an amazing technical vest but more of a casual outdoor-sy looking vest. I found the fit to be almost perfect for me (at a size six dress and a small/medium top). It is a little loose and I could easily wear a heavy sweater or a light jacket underneath but it is still fitted enough that it doesn't appear boxy on me when I just have a light tee.

I haven't tried hiking or snowshoeing in it yet but I don't think it will be super breathable, just more of a basic around town sort of garment.
