I received the vest a couple of weeks ago. While it has not been terribly cold here in northwestern WI in that period of time, I have had the opportunity to try it out on a couple of the chillier mornings. The fit is great given the side adjustments and the weight of the vest feels good to me - it is much heavier than a "puffer" vest. I think is going to be very nice in terms of layered outer wear as well.
I like vests and have multiple vests in the closet. This one is going to be one of my favorites.
