For me this sweatshirt is that "just right" balance of warmth and "breathable". For our long seasons that may be chilly but not freezing, this sweatshirt fits the bill. I have a vast collection of jackets and coats that go unworn because they are too warm and  just don't let moisture out. With any activity I find myself bathed in sweat. This Sweatshirt is well made, allows freedom of movement and seems to have that perfect balance I have not found elsewhere.
