I wore this during the cold wave in New York this past weekend with just a t shirt underneath. Was probably 0 degrees on the dot. Felt a little wind but overall comfortable. With my alpha sv on top was warm and comfortable. The weight 3was so light I was impressed how I barely felt it on me. Overall great piece but a little pricey.
