This jacket has an unbelievably high warmth to weight ratio. It's such a lightweight jacket, not to mention it stuffs into the chest pocket. I've been out in zero and single digits (F) with only a single layer underneath and it keeps me perfectly warm. Wind hasn't been an issue either. I'm very happy with this product and would purchase it again when need be.
