This is a sweater. It's a cotton knit. It uses original yarn that covers KODENSHI nylon with cotton cashmere. It's a special material that combines the excellent properties of each, such as the supple feel of cotton, the beautiful luster of cashmere, and the gentle warmth provided by the far-infrared technology of KODENSHI nylon. It's a cotton knit that can be worn like a sweatshirt. I think it's simple and easy to use.
