This jacket is incredibly light. It comes with a stuff sack that seems to be made out of the same material as the jacket. It is feather light. I wore it at camp in the morning and nights, with only a base layer underneath. The temperature was in the mid-to-high 30's and low 40's. I stayed very comfortable. No complaints what so ever from this product. Mont-Bell hit the nail on the head with this one.
