This jacket is light, and we do mean light: the 6.8-ounce, 90/10 poly/spandex fabric is lighter than many pullovers. In fact, this jacket goes so far as to offer a tag-free label and a zip-through cowl collar to offer the most insulation possible in a light jacket. With the ruching at the cuffs, the self-fabric hem, and the raglan sleeves, you'll look as stylish as ever even while feeling so comfortable you may just forget you have a jacket on in the first place.
