My first impression was that it is a little heavy. After using it a few time I realized that it is incredibly warm but it also regulates my body temperature well. When I wear a down jacket, I would often find myself sweating and removing my jacket. I had less of an issue with the Itinerant Jacket. It is a little on the pricy side but it is probably the same as buying a down jacket and a shell jacket. Plus, it is very thin.
