This compact jacket handles moderate temperature shifts with ventilated side panels and light insulation. Like lightweight fleece but designed with less bulk, the Atom SL allows for airflow but keeps out the cold and, at the same time, manages moisture. Strategically placed insulation keeps you warm, while water-resistant, hydrophobic materials have you ready for wet conditions.
