CPO Jacquard Shirt Midweight

How does the CPO Jacquard shirt in Midweight stack up against other WW outwear? Is it more of a layering piece where you wear it with other WW jackets ie the AAJ or Hoodorak or can it stand on its own in terms of warmth in this really cold weather? I’m in NJ and right now it’s about 5 degrees outside. I’ll wear a hoodie, a shirt underneath, my full weight AAJ, neck gaiter and beanie. I’m sure the CPO can be layered in this scenario but could I wear it by itself without the AAJ in these kinds of temps or is it better in above 32F weather or in the spring?
