Got this vest a couple of months ago after trying on many other products. It is very puffy and without a doubt the warmest vest per ounce of any I've tried including those by North Face, Marmot, MontBell etc. Quite surprising since it is made by Columbia, a company that is not usually thought of as a maker of high-end ultra-light gear. Total weight is 8 ozs on a digital postal scale and stuffs into its own pocket. This vest will keep you warm in all but the most extreme conditions.
