Thank you for viewing. This is a T-shirt purchased from Blue Ribbon Fly, a fly shop in Montana, USA. It was purchased about 20 years ago, so please understand that it is a used item. There is some fraying of the threads. The size is US-S, which I believe is equivalent to a Japanese M size. The color is yellow. Shoulder width: approximately 51cm Length: approximately 66cm Measurements are taken by hand, so please allow for slight variations.
