Wearing Sierra Designs' new Flex Down Jacket is like walking around in your comfiest, warmest sleeping bag, except you won't look half as silly. In fact, the goose down puffy incorporates Sierra's patented sleeping bag "Flex Technology," meaning the jacket moves with you while adapting to your shape to increase heat retention by reducing air space between you and your jacket. Fleece lined pockets up the cozy factor.
We love puffy jackets. We just wish they didn’t make us feel so, well, puffy. Therein lies the brilliance of Patagonia’s new barely there Nano pullover ($150). Three ounces lighter than Patagonia’s Down Sweater—a SKI staff favorite we were sure would never be unseated—the Nano’s synthetic PrimaLoft insulation retains heat even when wet. The wind- and moisture-resistant polyester shell is 100 percent recycled material and recyclable through Patagonia’s Common Threads program.
