These are the "MOUNTAIN LODGE DOWN PANTS" from Nanga, using 860FP Polish goose down (SPDX). The color is navy, and the size is L (please refer to images 12 and 13 for actual measurements). The condition is excellent, as they have only been tried on indoors. The outer shell is made of 10-denier ultra-thin nylon material, and the knees use a stretchy fabric, providing both durability and comfort. Weighing approximately 280g, they are lightweight but have a high loft, making them very warm down pants.
