I accidentally purchased this on Mercari. It's a light gray Mammut short-sleeved shirt. I think the condition is quite good. It's a Euro size M, which is an Asian size L. It feels smooth and is very light, and it dries quickly after washing and doesn't wrinkle easily, so it's also recommended for travel. Size: Asian size L Shoulder width: 40cm Body width: 50cm Length: 66cm Measurements are taken by a layman, laid flat. Please understand that there may be slight errors. Material: 100% polyester Thank you for your understanding regarding used items. Material: Polyester (synthetic fiber) Color: Gray Season: Spring/Summer
