DESCRIPTION

When lightweight core warmth is of the essence and you're planning on revving your aerobic engines, zip into the Arc'teryx Women's Atom LT Vest. The vest's cozy Coreloft synthetic insulation makes sure your core doesn't freeze, and at the same time, breathable Polartec panels let perspiration evaporate away. A body-skimming fit slips under outer layers easily if the clouds threaten. And since the vest packs into a tiny ball and weighs a paltry seven ounces, you needn't hesitate to pack it everywhere.
