These are comfortable Matsukan Katsujin Ori-zashi style jersey kote (wrist protectors). By using "HICool" (polyester), the same material used in jersey dogi (uniform) and hakama (trousers), for the surface, they can be dried in the sun after use. The sewing uses deodorizing thread Gunze Suitoru C, which helps to suppress odors. They are machine washable. They are soft and easy to use. Thank you for looking.
