This garment boasts high insulation, quickly absorbs and disperses sweat to keep your skin dry. The box construction, with a smooth outer layer and a soft inner layer connected by partitions, traps dead air (non-moving air as an insulation layer) to ensure warmth. The smooth surface allows for easy layering and smooth arm movement. Ideal for activities that involve repeated periods of activity and rest, such as mountaineering and ski touring. It's perfect for the cold seasons from autumn to spring.
