If the Patagonia Micro Puff above was just too heavy for you at a hefty 5.7 ounces, perhaps the 3.1-ounce Montbell Plasma 1000 will do the trick. This is not a misprint: the vest is made with 1,000-fill-power down, which is absolutely outrageous from a warmth-to-weight and fluffiness perspective. For serious alpine climbers or those who just want to brag about their down vest that weighs less than an average deck of cards, this is your ticket.
