I am going back and forth between the two jackets. I have always had a puffy but I have read so many good things about the Arcteryx Atom hoodie. With the hoodie I can hike with but I am unsure of the warmth while not hiking. With a puffy it is not as fun to hike with but I know the warmth will be there at the end of the day. I can only buy one. I plan on hiking Georgia in April and CT during the summer. What are your thoughts?
