The jacket is currently available in all medium, large, and extra-large sizes; even though it’s been restocked since its initial run, extra-small and small sizes have already flown off the site’s virtual shelves again. (It’s also sold out in plus-size options.) The stylish down alternative puffer has a sherpa-lined collar and cuffs, two zippered side pockets, and an interior drawstring. It retails for $120, and Amazon is currently the only major retailer you can shop it at. Because of the high demand, the jacket isn’t available for Prime’s two-day shipping, and is expected to arrive at your door within one or two months.
