This garment offers high insulation and quickly absorbs and disperses sweat, keeping your skin dry. The box construction, which connects a smooth outer layer and a soft inner layer with partitions, retains dead air (non-moving air as an insulation layer) to ensure warmth. The smooth surface allows for easy layering, making it easy to slide sleeves on and off. Suitable for activities that involve repeated periods of activity and rest, such as mountaineering and ski touring. It's ideal for the cold seasons from autumn to spring.
