This is a robe coat by arts & science. It's a piece made in Japan, featuring careful stitching and a luxurious combination of natural materials. The outer fabric uses yak, ramie, and wool. The yak provides lightness and high insulation, while the ramie adds a pleasant crispness, resulting in a material with depth that combines warmth and breathability. The collar is 100% wool rib knit, and the sleeve lining is cupro x cotton, a construction that pays attention to even the unseen parts. The front has no fasteners, and simply putting it on creates a natural drape, giving off the quiet presence that is characteristic of arts & science. It can be worn for a long time, from the change of seasons through winter, and can change its look depending on the inner layers. *Please note that there are a few small black holes, as shown in the last photo, where a badge was attached on the right chest.
