Purchased a few years ago at a MAMMUT directly-managed store. EU size S, Asian size M. This is a MAMMUT wool inner layer! Worn for one season. The navy color and red logo are rare now, and the design is also lovely. Because it's wool, you don't have to worry as much about sweat cooling or odors. (The right shoulder looks a bit white, but it's from clothespins, so I think it will come off with another wash!) Gender...Women's
