This navy item is likely to become a staple. I'm 174cm tall and weigh 64kg, and the fit is just right. Measured flat, the width under the armpits is about 48cm, the length is about 69cm, and the shoulder width is about 40cm. Please allow for slight variations due to amateur measurements. The material is mostly polyester, a smooth and quick-drying fabric. The retail price is 12,650 yen including tax.
