The soft feel of organic cotton and three-dimensional stitching allow for comfortable wear for long periods of time. The ear straps are adjustable, rather than elastic, which is constantly under tension. The size can be adjusted freely by tying a stopper knot. The subtle embroidered Hakutaku seal adds a touch of style. What is Hakutaku? The sacred beast Hakutaku was believed to ward off illness, and was extremely popular as a talisman to ward off evil and disease during the Edo period. Hakutaku is still enshrined as a deity at Gohyakurakan-ji Temple in Meguro, Tokyo. With three eyes on its face and three on each side, its somewhat humorous expression may be the reason it is so beloved.
