The R1 hoody has a 1/2 zipper or a bit more. I looked at the jacket and chose the 1/2 zipper option. I'm not crazy about jackets without hoods. They keep you warm and cut the wind even when it's warmish out. I also really like a hood in the mid-layers. When it's cold I'll wear 3 hoods layered over/under each other. I find it hard to be warm without a hood when it's cold.
