In 1999, a mountain guide who conquered all the famous mountains on the west coast of the United States for about 20 yearsestablished NUNATAK as a manufacturer specializing in down jackets. From material selection, sewing, down filling to product testing that makes use of his own experience and hobbies, he handles all processes by himself. Therefore, NUNATAK's products have a uniquely evolved perfection that is not bound by marketing or cost performance. A major feature of NUNATAK products is the down quilting method. By adopting a box structure that is mainly used for sleeping bags, it has higher heat retention than a normal down jacket. In addition, while normal manufacturers use a vacuum cleaner to fill in the down,NUNATAK measures the amount of down in a cup and fills it in by hand.Madein the most labor intensive way .
