Patagonia Nano Puff Vest - Women's

Yes, the Patagonia Women's Nano Puff Vest weighs almost nothing. But the difference it makes in your comfort level is noticeable to say the least. It's windproof, insulated with warm PrimaLoft insulation, and glides smoothly under your outer layers. You never knew that a 204-gram piece could boost your core warmth this much, but it can, and you'll want to stuff it into a little cranny of your backpack on every ski day, autumn climb, and chilly spring morning snowshoe.
