Gramicci's Sherpa Jacket has become a bit of a fan-favorite over the last couple of years, and it’s not that hard to see why. Made from sherpa fleece—which is that heavy-pile, sheepskin-style polyester fabric—it’s got a real classic vintage outdoor flavor, whilst still being super functional and useful today. It’s warm, it’s light and it looks great—the kind of thing that works just as well as a jacket in its own right as it does as a layer under a big coat.
