This is a navy and white short-sleeved shirt from White Mountaineering. It has a burgundy geometric pattern lining the collar. I loved it, but I no longer wear it due to my age. It's in very clean condition with no stains. It's made of 100% cotton, a thin and cool fabric. Shoulder width: 42cm, Body width: 50cm, Length: 70cm, Sleeve length: 22cm
