A zip up hoodie provides a versatility that the pullover version cannot match because the zip allows the hoodie to function as a layer that can be adjusted across a full range from fully closed to fully open without requiring it to be removed. This makes it more useful for the variable temperature situations that daily wearing involves. The zip needs to be quality enough to run smoothly across years of regular use without snagging or breaking. The fabric needs to hold its shape at the front opening as well as at the body. These are the zip up hoodies worth having as a genuine layering piece for the people who want the hoodie format to be as versatile as it can be.
