Whether we're layering for the resort or a run, we're zipping into Smartwool's Active Fleece Jacket. The exterior's polyester fibers dry off quick under spray and snowfall, while the interior's soft-brushed merino wool fibers trap warm air, wick away sweat, and stave off odors to keep us feeling our best. And with a four-way stretch and raglan sleeves, this jacket wouldn't dare hold us back.
