DownWool is an innovative high-end filling composed of 70% down and 30% wool. Down has a very high insulation capacity and a low weight. However, down only provides insulation as long as it is dry. With increasing humidity, the insulating effect of down is significantly reduced. The characteristic of wool is that it provides insulation and absorbs moisture. In this way, the down will stay dry and thus keeps its very high insulation capacity. With the unique mix of DownWool Grüezi-Bag achieves optimal insulation and a perfect dry sleeping climate with a low weight. The sleeping climate is decisive for sleep quality. The deeper and more relaxed your sleep, the more rested you will be the next morning.
