"The warmest option in the Atom series performs as a standalone or midlayer. Atom Series: Synthetic insulated midlayers. *The Atom Heavyweight Hoody was previously the Atom AR Hoody"This jacket is 2 years old and in great condition. I finally have a new one that actually fits me (different brand). This is size S/P, which means it fits shorter people great (< 5.8"). There is one small patch on the jacket, see photo.
